Question

Another researcher was interested in examining academic performance among teenage students. However, based on her literature review, she expected that ethnicity, parental support, and stress level would predict academic performance. Further, her study was based in New York.

Therefore, she collected data from one hundred and fifty (150) students from a school in New York. She hypothesized that parental support would positively predict academic performance, while stress would negatively predict academic performance. She also hypothesized that ethnicity would predict academic performance.

Parental support was measured with a twenty-item, seven-point Likert scale; stress was measured with the ten-item, five-point Perceived Stress Scale (PSS) ranging from Never to Very Often; and academic performance was measured as a percentage of the student’s average performance in the last academic year. Note that each Likert scale was summed and assume that higher numbers on each scale represents more of the respective variable. Ethnicity was coded in the data set as follows: 0 = Caucasian and 1 = Non-Caucasian.

After she collected, entered, and prepared her data for analysis, she conducted the appropriate statistical analysis in SPSS and below are her results. (Assume that the Likert scales were reliable and that all the necessary assumptions were met).

The researcher began interpreting her results in APA style as follows:

A multiple regression was conducted to determine if ethnicity, parental support and stress level would predict academic performance among teenage students in New York. The hypotheses were that ethnicity would predict academic performance, parental support would be a positive predictor of academic performance, and stress level would be a negative predictor of academic performance. Ethnicity, parental support and stress predicted 59% of variance in academic performance, R2 = .59, F (5, 294) = 84.59, p < .001.

QUESTION : Fully interpret the results between parental support and academic performance in APA style

Answer 1

QUESTION : Fully interpret the results between parental support and academic performance in APA style

Ans: The value of coefficient corresponding to the indepemndent variable Parental Support is 0.334 and more than 0. Also, the corresponding p-value for the two-tail test is 0.013. Therefore, the p-value for one tail test is 0.013/2=0.0065.Now, the p-value for the one tail test for B (coefficient of Parental Support) is grater than zero is 0.0065 and greater than 0.001 significance level. Hence, we have the sufficient evidence to conclude that parental support has a positively predict academic performance, Further, a unit increases on parental support, increase a unit on the mean of academic performance.
