Questions and Answers

What distinguishes True Experimental Design from Quasi-Experimental Design?

Quasi-Experimental Design relies on random selection of participants.

Quasi-Experimental Design is the best method for determining causal relationships.

True Experimental Design ensures objectivity and reduces bias. (correct)

True Experimental Design does not allow for control groups.

Which statement best describes Non-Experimental Research Designs?

They analyze how variables naturally exist without any alterations. (correct)

They can accurately determine causal relationships.

They require manipulation of variables to collect data.

They are only concerned with quantitative data.

What is the main purpose of the pre-test in experimental research?

To summarize the findings of the experimental group.

To identify initial differences between groups before treatment. (correct)

To manipulate the conditions affecting the experimental group.

To ensure the participants have similar backgrounds.

Study Notes

Research Design Types

Experimental Design: A research method based on experiments. Researchers manipulate variables to determine if hypotheses are valid. The experimental group receives the treatment, while the control group does not. This involves a pre-test for both groups and a post-test for the experimental group to measure treatment effects.
Experimental Group: Receives the treatment or manipulation.
Control Group: Does not receive any treatment.
Pre-test and Post-test: Both groups receive a pre-test. The experimental group receives a post-test to assess treatment effects.
Types of Experimental Designs:
- True Experimental Design: Uses random participant selection to minimize bias and accurately identify causal relationships.
- Quasi-Experimental Design: Selects participants purposefully, which might introduce bias and make it harder to establish cause-and-effect relationships.

Non-Experimental Design

Non-Experimental Design: Focuses on observing and gathering data on variables as they exist naturally without manipulation, often producing both qualitative and quantitative data, particularly in social sciences.
Data Focus: Primarily used to gather qualitative data, but also collects quantitative data. It's frequently used in social science research.
Types of Non-Experimental Designs:
- Descriptive: Provides a picture or profile of an individual or group.
- Comparative: Highlights differences or similarities among individuals, groups, or other phenomena.
- Correlative: Demonstrates the relationship between variables (positive or negative).
- Survey: Investigates the behaviors, preferences, opinions, and other characteristics of large populations.
- Ex Post Facto: Analyzes existing data from past events, without manipulation to explain past events. Literally translated from Latin means "after the fact."
