Fiona is a very busy graduate student. She is currently running 4 research studies by herself and volunteering at the local abused women shelter in her spare time.
One morning after a difficult night at the shelter, she provides one of her subject
pools with the research materials of one of her other experiments. After finding
out her mistake, she decides to cut-her loses and drop the data from that
morning's session. If Fiona decides to do this, what must she in turn do?
a. Request that the participants do her study again.
b. Document the error and inform others of the mistake.
c. Drop a similar number of participants from her other studies.
d. Nothing, she's done everything that is needed.
Question 2
The standard deviation of a distribution of means is sometimes called the standard error of the mean, or the standard error, because
A) it is an inaccurate estimate of a sample standard deviation and cannot be used to determine the variance.
B) it is calculated by summing the errors figured by subtracting sample means from the population variance.
C) it is frequently used as an error term when calculating the estimated sample variance.
D) it represents the degree to which particular sample means are in error as estimates of the mean of the population of individual scores.
