n − 1 

B 
(r1)(c1) 

C 
a chisquare distribution is not used

QUESTION 2
A goodness of fit test and test of independence is always conducted as a
A 
uppertail test 

B 
lefttail test 

C 
middle test 

D 
lowertail test 
QUESTION 3
The number of degrees of freedom for the appropriate chisquare distribution in a test of independence is
A 
number of rows minus 1 times number of columns minus 1 

B 
a chisquare distribution is not used 

C 
number of groups minus 1 

D 
sample size minus 1 
QUESTION 4
In order not to violate the requirements necessary to use the chisquare distribution, each expected frequency in a contingency table test must be
A 
at least 5 

B 
at least 10 

C 
no more than 5 

D 
less than 2 
QUESTION 5
The sampling distribution for a goodness of fit test is the
A 
Poisson distribution 

B 
chisquare distribution 

C 
normal distribution 

D 
t distribution 
Q1. The degrees of freedom for chisquare goodness of fit test is:
k  1
where k is the number of observed cells
Correct option: D) k  1
Q2. A goodness of fit test and test of independence is always conducted as a upper tail test because more the difference between the observed and expected values, more the statistic will shift towards the right and we will reject it.
Correct option: A) upper tail test
Q3. For chisquare test of independence:
df = (r  1) x (c  1)
r = number of rows
c = number of columns
Correct option: A)
Q4. In order not to violate the requirements necessary to use the chisquare distribution, each expected frequency in a contingency table test must be atleast 5
Correct option: A) at least 5
Q5. The sampling distribution for a goodness of fit test is the
B) Chisquare distribution
