In a psychology class, a teacher divided the class by what kinds of shoes they were wearing and then had each group make a list of why their shoes were better than the others. the fact that each group argued that they had the best shoes is an example of: a. in-group bias. b. discrimination. c. social facilitation. d. stereotyping.

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !
