New cards
2
Variable
Any characteristic, number, or quantity that can be counted or measured.
New cards
3
Qualitative Variables (Categorical Variables)
Variables that represent categories, groups, or labels without numerical value.
New cards
4
Nominal Variables
Categories with no inherent order or ranking (e.g., gender, types of fruits).
New cards
5
Ordinal Variables
Categories with a specific order but unequal intervals between them (e.g., education level, customer satisfaction ratings).
New cards
6
Quantitative Variables (Numerical Variables)
Variables representing measurable quantities expressed as numbers.
New cards
7
Continuous Variables
Variables that can take an infinite number of values within a given range (e.g., height, temperature).
New cards
8
Discrete Variables
Variables that take specific, distinct values, often whole numbers (e.g., number of children in a family, number of cars in a parking lot).
New cards
9
Population
The entire group or set of individuals, objects, or data points of interest in a study.
New cards
10
Parameter
A numerical value that summarizes a specific characteristic of a population.
New cards
11
Sample
A subset of the population selected for analysis.
New cards
12
Descriptive Statistics
Statistics that summarize a dataset using measures such as mean, median, mode, range, variance, and standard deviation.
New cards
13
Inferential Statistics
Techniques used to draw conclusions or make predictions about a population based on a sample.
New cards
14
Univariate Analysis
Analysis focused on a single variable, examining distribution, central tendency, and spread.
New cards
15
Bivariate Analysis
Analysis examining relationships between two variables (e.g., correlation between education level and income).
New cards
16
Multivariate Analysis
Analysis dealing with three or more variables to explore complex relationships.
New cards

Slovin’s Formula

where:

  • n = sample size

  • N = total population

  • e = margin of error

This is used to determine sample size.

<p>where:</p><ul><li><p>n = sample size</p></li><li><p>N = total population</p></li><li><p>e = margin of error</p></li></ul><p></p><p>This is used to determine sample size.</p>
