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 ...
