- For the following variables, identify which is the Independent
Variable and the Dependent Variable. Then create a hypothesis (be
sure to also include the direction of the relationship) and then
create a null hypothesis.
- Temperature and crime rates
- Hours studied and test scores
- Number of police officers and crime rate
Solutions
Expert Solution

Hypothesis: There is a positive relationship between hours studied and test scores.
Null hypothesis: There is no relationship between hours studied and test scores.
Number of police officers and crime rate
Number of police officers is the independent variable and crime rate is the dependent variable.
Hypothesis: There is negative relationship between Number of police officers and crime rate.
Null hypothesis: There is no relationship between Number of police officers and crime rate.

Refresher on Variables:
Classifying variables as independent or dependent:
The independent variable is the one being
manipulated or grouped in the study for comparison. A tip to
remember this is to think that independent starts with “I” and I,
the researcher, manipulate that variable or have control over who
is grouped in the study. The way we will be using independent
variables in this course is in terms of between group analysis, so
our focus will be on groups being...
