Which is not a study design?

​

Correct option is B

Interview

The term study design refers to the overall strategy or structure used to conduct research. It outlines the plan for how data will be collected, analyzed, and interpreted in a research study. The study designs typically include:

1. Cross-Sectional Design – This study design involves collecting data at a single point in time from different groups or individuals. It is useful for comparing different variables or groups but does not provide insights into changes over time.
2. Cross-Cultural Design – This design compares different cultures or cultural groups to understand how cultural differences or similarities affect various phenomena. It often involves analyzing data from multiple cultures at once.
3. Longitudinal Design – This type of study design involves collecting data over an extended period, typically to examine how certain variables or groups change over time. It is particularly useful for studying trends or the development of particular outcomes over time.

An interview is not a study design itself but rather a data collection method. Interviews are commonly used in both qualitative and quantitative research to gather in-depth information from individuals, but they are a tool used within various study designs.

Information Booster:

1. Cross-Sectional Study – A snapshot of a population or phenomenon at a single point in time. It helps researchers examine relationships between variables or compare different groups.
2. Cross-Cultural Study – Researchers compare different cultural or societal groups, typically to examine universal versus culture-specific behaviors, values, and practices.
3. Longitudinal Study – Focuses on data collected over a period of time (months or years), allowing researchers to study the development or changes in participants, behaviors, or trends.
4. Interviews as Data Collection – Interviews can be structured, semi-structured, or unstructured depending on the research needs, but they are considered methods for data collection rather than a study design.

Additional Knowledge:

• Cross-Sectional Design is used to analyze data at one point in time, often for descriptive studies, while Longitudinal Studies are essential for observing long-term effects and trends.
• Interview is one of the most common qualitative data collection methods, but it is a technique that can be applied within a variety of study designs.
