Are the results of the following study statistically significant? If so, why?
A psychologist performs an experiment to see if she could condition a group of third graders to associate doing math with the positive feeling of eating sugar. For a one semester, she gave pieces of candy to students doing math problems in one classroom, while giving nothing to students in a neighboring classroom. She observed that all of the students in the study class associated candy with doing math by the end of the semester. She performed the same experiment the following year with a different class and had similar results.
A)
The results of this study are not statistically significant.
B)
Yes, because the results were overwhelmingly positive.
C)
Yes, because of the sample size.
D)
Yes, because the results were important.
E)
Yes, because the experiment was repeated.
And your answer?
E)
Yes, because the experiment was repeated.
I agree.
From the given information, it is not possible to determine whether the results of the study are statistically significant. The options provided do not accurately assess the statistical significance of the study. To determine statistical significance, several factors need to be considered, such as the sample size, the experimental design, and the analysis of the data.
In this scenario, the information mentions that the psychologist performed the experiment with two different groups of third graders in two separate years, and observed that all the students in the study class associated candy with doing math by the end of the semester. However, this information alone is not sufficient to determine statistical significance.
To determine statistical significance, it is necessary to compare the results between the two groups (study class and neighboring class) statistically. A statistical test, such as a chi-square test or t-test, would need to be performed on the data collected from both years to assess if the differences in the associations were statistically significant or simply due to chance.
Therefore, the correct answer is not provided among the options provided. Further information or analysis would be required to determine the statistical significance of the results.
