In this chapter, the experiments set out to test whether physical fitness, life stress, and health are directly related to each other. To test this, the researcher used correlational studies. Correlational research is an investigation of the relationships between two variables. The data found is reported as a correlation coefficient, which is measured on a scale from -1.00 to 1.00. The strongest relationship is negatively or positively as close to 1.00 as possible. The weakest relationship is positively or negatively as close to 0 as possible. A correlation with a negative value shows an inverse relationship while a positive value shows a relationship where variables fluctuate together. A strong relationship is important because it allows a researcher to make a quite accurate prediction of the value of one variable if they know the other value. However, a strong relationship does not necessarily mean that there is a causal link between the variables.
The participants involved in the experiment were a group of introductory psychology students who were followed for a college academic year. The group numbered 110 and was composed of 37 males and 73 females. Ninety of
