Question 9

Previous research studies showed that the mean learning performance of college students is 64 out of 100 when they are presented with static illustrations along with textual information. A researcher is interested in whether using animations instead of static illustrations would increase learning performance. She collects data from 31 college students. The dataset can be found in the Excel file.

Considering the research results for the study above, which of the following results are correctly reported in APA format?

  • A. A one-sample t-test was used to analyze data. Results showed that the students who studied with animations scored higher (M = 83.45, SD = 6.58) compared to the students in general (t(31) = 16.47, p < .05, d = 2.96).
  • B. A one-sample t-test was used to analyze data. Results showed that the students who studied with animations scored higher (M = 83.45, SD = 6.58) compared to the students in general (M = 64.00; t(30) = 16.47, p < .05, d = 2.96).
  • C. A z t-test was used to analyze data. Results showed that the students who studied with animations scored higher (M = 83.45, SD = 6.58) compared to the students in general (M = 64.00; t(30) = 16.47, p < .05, d = 2.96).
  • D. A one-sample t-test was used to analyze data. Results showed that the students who studied with animations scored higher (M = 83.45, SD = 6.58) compared to the students in general (M = 64.00; t(30) = 16.47).
  • E. A one-sample t-test was used to analyze data. Results showed that the students who studied with animations scored higher (M = 83.45, SD = 6.58) compared to the students in general (M = 64.00; t(30) = 16.47, p < .05, d = 2.96).
