Study Notes

Scales of Measurement

A nominal scale reflects categorization with no inherent order or equal differences, distinguished from other scales by lacking any magnitude or order.
An ordinal scale consists of categories organized in an ordered sequence.
An interval scale reflects equal differences between numbers in magnitude but lacks an absolute zero point.
A ratio scale has an absolute zero point, differentiating it from an interval scale.

Data Collection

Researcher-completed instruments involve researchers collecting data directly from participants.
Subject-completed instruments involve participants completing questionnaires or surveys themselves.

Questionnaires

The purpose of a rating scale is to quantify opinions, attitudes, or behaviors.
A questionnaire is used to collect self-reported data from participants.
When designing a questionnaire, avoid leading questions and ensure clarity and concision.
The principle of starting with demographic questions helps to build rapport and increase respondent engagement.

Statistical Analysis

Cochran's correction formula is used to adjust the chi-square value when there are expected frequencies less than 5.
In Cochran's formula, 'p' represents the population proportion.

Research Design

An independent variable is the variable manipulated by the researcher to observe its effect on the dependent variable.
Data collected in a study are collectively referred to as observations or measurements.

Statistics

Yamane's formula determines the sample size required for a study.
