Introduction to Quantitative Research

Practice questions covering the characteristics, advantages, and disadvantages of quantitative research based on the lecture transcript.

What is the definition of quantitative research?

Quantitative research uses scientifically collected and statistically analyzed data to investigate observable phenomena.

Why is a large sample size required in quantitative research?

To obtain more meaningful statistical results, as data must come from a large sample size.

What does 'objectivity' mean in the context of quantitative research characteristics?

Data gathering and analysis of results are done accurately and are unaffected by the researcher's intuition and personal guesses.

What visual tools are used for the concise presentation of numerical data in quantitative research?

Graphs, charts, and tables.

How does quantitative research achieve faster data analysis?

Through the use of statistical tools which allow for less time-consuming analysis.

When can data from a sample be applied to a general population?

If sampling is done accordingly, meaning sufficient size and random samples were taken.

What type of instruments allow researchers to collect data from large sample sizes efficiently?

Standardized research instruments, such as a single survey form administered simultaneously.

What is high replicability in quantitative research?

The ability to repeat the method to verify findings, which enhances validity and prevents false or immature conclusions.

What is a major advantage of quantitative research regarding outcomes?

Numerical and quantifiable data can be used to predict outcomes.

What type of relationship can be conclusively established using quantitative research?

The conclusive establishment of cause and effect.

List one disadvantage of quantitative research regarding the depth of a problem.

It lacks the necessary data to explore a problem or concept in depth.

Why does quantitative research fail to provide a comprehensive explanation of human experiences?

Because some information, such as feelings and beliefs, cannot be described by numerical data.

How is the research design of quantitative studies characterized in terms of flexibility?

The research design is rigid and not very flexible.

What is a limitation placed on participants in a quantitative study?

Participants are limited to choosing only from the given responses and may tend to provide inaccurate responses.

What makes quantitative data collection more costly?

A large sample size.
