DISPLAY DESIGN: A HUMAN FACTOR OF SPACEFLIGHT
 
Statistics

Key Topic: Hypothesis Testing

When astronauts view control panels with multiple labels, they may need to pick out a particular label value from a display. An experiment was conducted to compare response times for right vs. left alignment of labels. Students will evaluate the data compiled from this experiment and perform a hypothesis test to determine whether there is a difference in the response times that would indicate one being preferred over the other.

Students will
  • construct null and alternative hypotheses to analyze the response times for left-aligned vs. right-aligned labels;
  • choose an appropriate hypothesis test;
  • check assumptions necessary to conduct the hypothesis test;
  • perform the hypothesis test; and
  • draw the correct conclusion based on the results of the test.
