Sampling Methods
Sampling refers to selecting a subset from a population.
Probability Sampling
Simple Random Sampling
Each member has an equal chance of selection.
Systematic Sampling
Every nth item is selected.
Stratified Sampling
Population is divided into homogeneous groups called strata.
Cluster Sampling
Population is divided into clusters, and clusters are selected randomly.
Non-Probability Sampling
Convenience Sampling
Selection based on ease of access.
Purposive Sampling
Selection based on researcher’s judgment.
Snowball Sampling
Used for hidden or difficult-to-reach populations.
Quota Sampling
Population is divided into groups and samples are selected according to quotas.

Measurement Scales
Nominal Scale
Used for classification only.
Examples:
- Gender
- Religion
- Blood Group
Ordinal Scale
Used for ranking.
Examples:
- Class Rank
- Satisfaction Level
Interval Scale
Equal intervals but no true zero.
Examples:
- Temperature (Celsius)
Ratio Scale
Contains an absolute zero.
Examples:
- Height
- Weight
- Income
Important UGC NET Fact: Ratio Scale is the only scale with a true zero.
Statistical Concepts
Mean
Average of observations.
Formula
Mean = Sum of Observations / Number of Observations
Median
Middle value in an ordered dataset.
Mode
Most frequently occurring value.

Standard Deviation and Variance
Variance
Measures the spread of data from the mean.
Standard Deviation
Square root of variance.
Important Formula
Variance = (Standard Deviation)²
Normal Distribution
Important facts:
- Mean = Median = Mode
- Bell-shaped curve
- Symmetrical distribution

Standard Normal Distribution
- ±1σ = 68%
- ±2σ = 95%
- ±3σ = 99.7%
These values are frequently asked in UGC NET examinations.

Research Design
Research design is the blueprint of a study.
Types
- Exploratory Research Design
- Descriptive Research Design
- Diagnostic Research Design
- Experimental Research Design
APA Referencing Style
APA stands for American Psychological Association.
Book Reference Format
Author’s Last Name → Year of Publication → Title → Publisher
Example
Sharma, A. (2024). Research Methodology. XYZ Publications.
Important questions are frequently asked regarding the sequence of APA referencing.
