Applying Analytical Strategies to a Research Area of Interest
ANALYTICAL STRATEGIES APPLICATION
Statement of research area of interest
The study consists of a sample of selected couples who are randomly assigned into two
experimental therapy groups and one control group. The research area of interest entails
comparing the two different types of couple therapy with each other as well as a control group
that does not receive treatment. The results are analyzed to assess the effectiveness of the therapy
treatment on the couples. The analytical strategies used are correlation and regression.
Pearson correlation attempts to measure the strength of a linear relationship between two
variables by drawing a line of best fit through the values of two chosen variables (Bolboacaet al.,
2006). The two variables suitable for the computation of the Pearson correlation coefficient, r,
are treatment results values and couple therapy “1” experiment values. The scale of measurement
for the two variables is Ratio since they are of equal intervals and satisfy the absolute zero
property, are normally distributed and linearly related.
Assuming a Pearson correlation coefficient of (r = 0.79) and the observed sample size is 30
we can deduce that “A Pearson product-moment correlation was run to investigate the
association between treatment results and couple therapy “1”. There was a strong, positive
correlation between the two variables, which was statistically significant (r = .79, n = 30, p =
.005). From the Pearson c...
