Question
A clinical psychologist is concerned that the social-isolation necessitated by the
pandemic is increasing the number of symptoms experienced by her patients with
anxiety disorders. The psychologist randomly selects 5 of her patients with Generalized
Anxiety Disorder (GAD) and compares the severity of symptoms that they experienced
right before self-isolation began, one week into self-isolation, two weeks into self-
isolation, and three weeks into self-isolation. Symptom severity was measured with the
Generalized Anxiety Disorder Severity Scale (GADSS) which ranges from 0 to 24, with
higher numbers representing greater severity of symptoms (you don't need this to
answer the question, but just in case you are interested). Is there sufficient
evidence to indicate, at the 5% level of significance, that increased time in self-isolation
increases the severity of GAD symptoms?
Use the data recorded below and SPSS to answer the following questions.

test?
○ Ho: μB = μ1 = fl2 = fl3
H₁: Not Ho
○ Ho: µB ‡µ₁ ‡µ₂ ‡ µ3
H₁: µB = µ₁ = fl2 = fl3
○ Ho: μB = μl1 = fl2 = fl3
H₂: µB ‡µ₂ ‡µlz #flz
○ H₁: μB = μl1 = flz = flz
Ho: Not H₁
Step 2: What is cx? Round your answer to 2 decimal places.
Step 3: Use SPSS to find SSBetween. Round to the 2nd decimal place.
Step 3: Use SPSS to find SS Error. Round to the 2nd decimal place.
