Question:

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.

Based on the information above, which of the following would be a well-formed alternative hypothesis for this research study?

  • A. College students who study with animations will score the same compared to the students in general.
  • B. College students who study with animations will score higher or lower compared to the students in general.
  • C. College students who study with animations will score higher compared to the students in general.
  • D. College students who study with animations will score lower compared to the students in general.
  • E. College students who study with animations will not score the same compared to the students in general.

Answer:
C. College students who study with animations will score higher compared to the students in general.

Reason
This is a one tailed test since the study is aimed at testing whether study with animations is better than static illustrations along with textual.
