1. If I were designing my research study in the field of psychology, I would most likely use a t-test as the method of data analysis. A t-test is best used when the researcher wants to determine deviations from a normal distribution curve. If there are one or more normal distributions (bell curves), t he researcher can compare the two groups using the t-test method. The variances do not need to be known to perform a t-test either, which is another reason why I would select this method of data analysis in my particular research question. Furthermore, the researcher can use the t-test to measure the differences between two populations regardless of how small or large the sample size. The t-test, also known as the student t-test, is one of the best methods applied to studies using a small sample size. If my research were to progress to where I needed to use a larger sample size, then I would need to move onto other types of data analysis like a z-test or chi-square. The t-test ultimately uses simple mathematics such as ratios to calculate the differences between the experimental and control groups, or between two comparison groups. For example, if I were studying the difference between men and women on a certain psychological construct or on the basis of their reactions to come stimuli, then I could use a t-test. The t-test results would be able to tell me if it was indeed gender that was accountable for the differences in their reactions to the stimuli, as opposed to some...
Likewise, I could compare different age groups or anything that would allow for me to determine if there was an effect caused by the independent variable. After applying the t-test to my initial research design, I could then design a more robust study with even greater reliability and validity.

It is important to look at this issue as it relates to body image and how one feels about one's body, but also important to see it in the light of the way that one trust's oneself

Regression, Correlation: Effect of IQ on GPA Effective teaching begins with understanding the thinking and reasoning abilities of one's students and devising ways to ensure that the classroom setting is accommodative of the inherent differences in cognitive capabilities and that all students get to benefit from the learning process.
