Transcribed Image Text:An und Tuate student performed a visual experiment on a number of participants. Since the experiment involved displays of colored letters and
backgro after the experiment the student wondered whether the presence or absence of color vision in the participants could have produced some of the
effects seen in the data. The student went back, tested his participants for colorblindness, and reanalyzed the data. He considered the variables color vision of
participant ("colorblind" or "not colorblind") and trial outcome ("hit", "miss", "false alarm", or "correct rejection").
The contingency table below gives a summary of the data from 2000 trials of the experiment. Each of the trials was performed either by a colorblind
participant or a non-colorblind participant. Each cell of the table contains three numbers: the first number is the observed cell frequency (f); the second
number is the expected cell frequency (f) under the assumption that there is no dependence between the two variables color vision of participant and trial
outcome; and the third number is the following value.
(fo-fe)² (Observed cell frequency - Expected cell frequency)²
JE
Expected cell frequency
The numbers labeled "Total" are totals for observed frequency.
