Discussing Experimental Research Design

An experimental study has been designed to determine the effectiveness of a new reading program on the reading comprehension of first-grade students. As a researcher, discuss each of the following:

1. Likely sampling technique.
2. Possible research hypotheses (both non-directional and directional).
3. Extraneous variables that should be considered and ways to control for those variables.
4. Ways you might operationally define your dependent variable.
5. What you would need to know about the treatment or independent variable.

Provide any references as necessary.

An experimental study has been designed to determine the effectiveness of a new reading program on the reading comprehension of first-grade students. As a researcher, discuss each of the following:

1. Likely sampling technique.

The likely sampling technique that will be used in such as experimental study will entail one that is predicated upon utilizing the random sampling method. This method is being used more in the research because of the larger experimental policies that research studies have regarding appropriating the use of randomly assigned individuals within the experiment to allow for the control or treatment groups.

2. Possible research hypotheses (both non-directional and directional).

Nondirectional Hypotheses are ...
