◉ A result is considered statistically significant when
a) the sample score is so extreme that the research hypothesis is
rejected
b) the sample score is so extreme that the null hypothesis is rejected
c) the population mean is so extreme that the research hypothesis is
rejected
d) the population mean is so extreme that the null hypothesis is
rejected. Answer: The sample score is so extreme that the null
hypothesis is rejected
◉ The item below is based on the following scenario:
A health psychologist is interested in the effectiveness of a anew
exercise on reducing the rate of heart attacks because the exercise
requires no equipment, and therefore, can be done without cost.
What is the research hypothesis?
a) people will participate because it does not cost them any money
b) the exercise will make a difference in the rate of heart attacks
c) the exercise will reduce the rate of heart attacks
d) the exercise will increase the rate of heart attacks. Answer: The
exercise will reduce the rate of heart attacks
,◉ The item below is based on the following scenario:
A health psychologist is interested in the effectiveness of a anew
exercise on reducing the rate of heart attacks because the exercise
requires no equipment, and therefore, can be done without cost.
What is the comparison distribution?
a) the distribution of people who participate in the exercise program
b) the distribution of people who do not participate in the exercise
program
c) the distribution of people who have heart attacks
d) the distribution of people who do not have heart attacks. Answer:
The distribution of people who do not participate in the exercise
program
◉ A psychologist who rejects the null hypothesis - because the
probability of obtaining the results if the null hypothesis is true is
less than 5% - would express this finding in symbols as
a) p = 5%
b) p < .05
c) .05 < p
d) p > 5%. Answer: P < .05
◉ The conventional levels of significance in hypothesis testing in
psychology are
, a) .001 and .01
b) .01 and .05
c) .10, .20, and .30
d) .05, .25, and .95. Answer: .01 and .05
◉ The distribution that represents the situation in which the null
hypothesis is true is
a) the comparison distribution
b) the sample distribution
c) a two tailed distribution
d) a one tailed distribution. Answer: The comparison distribution
◉ Rejecting the null hypothesis at the .05 level means that
a) there is more than a 5% chance of getting such an extreme result
if the null hypothesis is true
b) there is more than a 95% chance of getting such an extreme result
if the research hypothesis is true
c) there is less than a 5% chance of getting such an extreme result if
the null hypothesis is true
d) there is less than a 95% chance of getting such an extreme result
if the research hypothesis is true. Answer: There is less than a 5%
chance of getting such an extreme result if the null hypothesis is
true.
