Before the start of her psychology exam, Sally begins to sweat and her heart rate increases. She interprets that her arousal must be due to the fact that she is unprepared for the exam, so she becomes anxious.

Two-Factor Theory

Explanation:

The two-factor theory is also referred to as Schachter- Singer theory of emotion; this theory tries two explain that there are two factors required to experience an emotion. The first factor is "physical arousal" or physiological response as a result of an environmental stimulus. The second factor is then the cognitive response that tries to interpret the initial physiological response.

In the case of Sally, the first factor was her increased sweat and heart rate as a result of the exam, while the second was her cognitive processes which interpreted her increased heart rate due to the fact that she is unprepared for the exam.

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 !
