Practical Research: Methodology, Design, and Data Analysis

Comprehensive practice flashcards covering quantitative research concepts, literature review methodologies, research design and sampling, instrument validation, and statistical analysis and findings from the study on emotional quotient and purpose in life among prisoners.

What are the key characteristics that define quantitative research?

Quantitative research is objective, relies on clearly defined research questions, uses structured research instruments, gathers numerical data, involves large sample sizes, permits replication, and predicts future outcomes.

How does descriptive research differ from correlational research?

Descriptive research describes the nature, characteristics, and components of a population or phenomenon without manipulating variables or establishing cause and effect. Correlational research systematically investigates relationships or associations between variables without necessarily examining underlying causal reasons.

What is the operational difference between cross-sectional and longitudinal survey research?

Cross-sectional survey research collects data from a sample at a single point in time, whereas longitudinal survey research collects data from the same subjects repeatedly over an extended period, sometimes lasting many years.

What characterizes causal-comparative (ex post facto) research?

Causal-comparative (ex post facto) research derives conclusions from observations and manifestations that have already occurred in the past by comparing pre-existing group characteristics to dependent variables.

What distinguishing features separate true experimental, quasi-experimental, and pre-experimental research designs?

True experimental designs include random assignment of participants from a population to experimental and control groups, with active manipulation of treatments. Quasi-experimental designs feature manipulation and control groups but restrict randomization to pre-assigned groups. Pre-experimental designs have no randomization, no random assignment of treatments, and typically lack control groups.

How does a mediating variable differ from a moderator variable?

A mediating (intervening or go-between) variable explains the relationship by transmitting the effect from the independent variable to the dependent variable. A moderator variable alters the strength or direction of the relationship between the independent and dependent variables at different levels.

What is the difference between an extraneous variable and a confounding variable?

An extraneous variable is any undesirable variable not intentionally studied that can compete with the independent variable in explaining the outcome. It becomes a confounding variable when it is proven to be the actual cause of the outcome.

How are continuous variables categorized into interval and ratio variables?

Interval variables have meaningful differences between values but no true zero point (e.g., temperature). Ratio variables possess all properties of interval variables and additionally feature a clear, absolute definition of zero indicating the complete absence of the measured variable (e.g., height, weight).

What distinction separates nominal variables from ordinal variables?

Nominal variables have no quantitative value and are used strictly for labeling or classifying categories (e.g., gender, religion). Ordinal variables consist of categories that can be placed in a meaningful ranked order (e.g., contest winners).

What four core elements must be presented in the introduction of Chapter I?

The introduction must discuss: 1. Topic or subject matter; 2. Importance of the topic; 3. Reason for choosing the topic; and 4. Purpose of the study.

According to the Bureau of Corrections and BJMP in 2011, what was the allocated daily subsistence allowance per prisoner?

Prison administrators allocated a daily subsistence allowance of $\text{₱}50$ per prisoner as of $2011$.

What is the technical distinction between a null hypothesis ($H_0$) and an alternative hypothesis ($H_a$)?

A null hypothesis ($H_0$) states that there is no relationship or effect between variables and serves as the statement tested statistically. An alternative hypothesis ($H_a$) states that the observed observations are the result of a real effect or relationship.

What is the difference between scope and delimitation in a research study?

Scope defines the coverage of the study in terms of concepts, number of subjects, and timeline. Delimitation refers to the specific factors, variables, time frames, or populations deliberately excluded or not dealt with by the researchers.

How does a conceptual definition differ from an operational definition in research?

A conceptual definition provides the dictionary or theoretical meaning of a construct. An operational definition specifies how the construct is uniquely applied, measured, or manipulated within the context of the study.

What is the distinction between conceptual literature and research literature in Chapter II?

Conceptual literature consists of non-empirical or data-free materials from books, journalism, and related writings. Research literature comprises empirically based studies, scientific papers, theses, and dissertations.

What criterion regarding publication date must materials cited in a literature review satisfy?

Cited materials must be current, dating back at least $6$ years from the conduct of the study.

What are the etymological origins and meanings of the words 'journal' and 'article'?

Journal comes from the Latin word 'diurnalis' meaning 'daily' and refers to a scholarly periodical aimed at specialists. Article derives from the Latin 'articulus' ('small joint') and Old French 'article' ('separate part of anything written'), denoting a full-length document on original research.

What are the defining characteristics of an integrative literature review?

An integrative review is the most common form of literature review; it reviews, critiques, and synthesizes representative literature on a topic in an integrated way to generate new frameworks and perspectives.

How must citations for works with two authors and works with three or more authors be formatted in text?

For two authors, both surnames must be cited every time using 'and' in narrative text or '&' in parenthetical citations. For more than two authors, all authors are listed the first time, while subsequent citations list the first author's surname followed by 'et al.' and the year.

What three core dimensions comprise the theoretical model shown in this diagram?

The three dimensions are the Personal Dimension, the Social Dimension, and the Emotional Dimension.

What do the three elements of the Input-Process-Output (IPO) model represent in a research paradigm?

Input represents the respondents and their demographic profile; Process represents how the research is conducted (administration of instruments and data analysis); Output represents the expected results, conclusions, and recommendations.

What are the two fundamental purposes for writing Chapter III (Research Methodology)?

Chapter III is written with two purposes in mind: to enable a competent reader to replicate the study and reproduce its results, and to evaluate whether the study adhered to a valid scientific process.

What formula is shown in this image, and what does each variable signify?

This is Slovin's Formula, $n = \frac{N}{1 + Ne^2}$, used to determine optimal sample size, where $n$ is the sample size, $N$ is the population size, and $e$ is the margin of error.

What is sampling error and how does sample size influence it?

Sampling error occurs when the selection of a sample does not proceed as planned, leading to over-representation or under-representation of segments of the population. A larger sample size reduces sampling error.

According to this organizational diagram, what are the four non-probability sampling techniques and the four probability sampling techniques?

Non-probability techniques are Convenience Sampling, Purposive Sampling, Quota Sampling, and Snowball Sampling. Probability techniques are Simple Random Sampling, Systematic Random Sampling, Stratified Random Sampling, and Cluster Sampling.

How does convenience sampling differ from purposive sampling?

Convenience (accidental) sampling selects participants based purely on convenience to the researcher (e.g., stopping passersby). Purposive (judgmental) sampling selects participants based on specific researcher-defined criteria relevant to the research topic.

In systematic random sampling, how is the sampling interval width ($k$) calculated?

The sampling interval width is calculated by dividing the known population size ($N$) by the desired sample size ($n$): $k = \frac{N}{n}$. Every $k^{\text{th}}$ element on the population list is then selected.

What four primary ethical considerations must be observed when conducting research with human subjects?

The four ethical considerations are: 1. Intellectual property; 2. Informed consent; 3. Respect for confidentiality and privacy; and 4. Maintaining anonymity.

What is the technical distinction between reliability and validity in research instrumentation?

Reliability refers to the consistency and repeatability of the instrument's measurements. Validity refers to the accuracy of the instrument, indicating whether it genuinely measures what it intends to measure.

What are the structural specifications of the Bar-On EQ-i:S instrument used to measure emotional quotient?

The Bar-On EQ-i:S consists of $51$ items across five scales: Intrapersonal EQ, Interpersonal EQ, Stress Management EQ, Adaptability EQ, and General Mood EQ. It provides norms for males and females across four age groups and can be completed within $30$ minutes.

What are the structural properties of the Purpose in Life (PIL) Test Questionnaire used in the prison study?

The PIL was formatted into a $40$-item scale rated on a $7$-point Likert scale, with total scores ranging from $20$ (low purpose) to $140$ (high purpose). It comprises three scales: Perceptions of Life, Personal Aspirations, and Interest in Living.

According to the factor analysis by Morgan and Farsides (2009), what two factors were retained for the Purpose in Life (PIL) test?

Morgan and Farsides retained two factors: 'exciting life' (items $2$, $5$, $7$, $10$, and $17\text{–}19$) and 'purposeful life' (items $3$, $8$, and $20$).

What are the verbal interpretations corresponding to the mean ranges in a 5-scale Likert system?

$1.00\text{–}1.49$ = Very Low; $1.50\text{–}2.49$ = Low; $2.50\text{–}3.49$ = Average; $3.50\text{–}4.49$ = High; and $4.50\text{–}5.00$ = Very High.

What were the demographic distributions by age and gender among the 60 inmate respondents in the research study?

By age: $28\text{–}37$ years old had the highest frequency at $38\%$ ($f = 23$), followed by $18\text{–}27$ at $27\%$ ($f = 16$), $38\text{–}47$ at $23\%$ ($f = 14$), and $48\text{–}57$ at $12\%$ ($f = 7$). By gender: males accounted for $85\%$ ($f = 51$) and females accounted for $15\%$ ($f = 9$).

What notable finding was revealed regarding item 9 of the Intrapersonal scale among the inmate respondents?

Item 9 ('Mahirap para sa aking ilarawan ang aking mga nararamdaman') scored 'High' with a weighted mean of $3.53$, demonstrating that the inmates had a poor ability to recognize and describe their own emotions, aligning with Haney's (2009) Psychological Effects of Imprisonment.

What did the study conclude regarding the relationship between inmate demographics and their emotional quotient versus purpose in life?

Demographic profiles (age, gender, incidence of imprisonment, violated law) had no bearing on emotional states. However, gender was found to influence perceptions of life, while stress management and intrapersonal skills directly influenced the prisoners' overall purpose in life.
