Question: Question 1:

For each of the 6 examples (a-f), you need to provide the following answers:

A) the conditions of the independent variable (if you want to name the IV too, that's fine, but make sure you list the conditions)

B) the scale of measurement for the IV

C) the dependent variable

D) the scale of measurement for the DV

E) the measure of central tendency you would use in this specific example

F) the measure of variability you would use in this specific example

(NOTE for 5 & 6: make sure you consider the variables that influence your choice for the measures of central tendency and variability)

G) which scores you would use to compute the measure of central tendency and variability

a) We test whether participants laugh longer (in seconds) to jokes told on a sunny or rainy day.

b) We test babies whose mothers were or were not recently divorced, measuring whether the babies lost weight, gained weight, or remained the same.

c) We compare a group of adult children of alcoholics to a group whose parents were not alcoholics. In each, we measure the participants’ income.

d) We count the number of creative ideas produced by participants who are paid 5, 10, or 50 cents per idea.

e) We measure the number of words in vocabulary of 2-year-olds as a function of whether they have 0, 1, 2, or 3 older siblings.

f) We compare people 5 years after they have graduated from either high school, a community college, or a four-year college. Considering all participants at once, we rank order their income.
