Question

Angela created and maintains an exercise app where users log their workouts. She wonders if sending users a daily notification that reminds them to use the app will result in them logging more workouts. She releases an update to her app so that half of users will have daily notifications and the other half won't have daily notifications (randomly determined for each user). After a few weeks, she'll see if one group logs more workouts on average than the other group.
What type of study is this, and what is the response variable?

Answer 1

It is an experimental study (experimental design) and the response variable is the number of workouts. The response variable refers to the results of the experiment.

Experimental design and response variable

Experimental design refers to the set of conditions in which a given experiment has been conducted in order to collect empirical evidence.

The response variable refers to the result of a given experiment where an explanatory variable has been manipulated.

A response variable refers can be a variable in which the scientist is making a question, which can be answered after experimentation.
