A study was done to determine whether or not taking Stat 121 will increase the chances of getting into one’s preferred major. 100 students participated in this study, 50 were randomly assigned to take Stat 121 and the other 50 did not take Stat 121. After the semester the students applied for their major choice and it was recorded whether or not the student got into the major. a)What is the response variable? Whether or not the student was assigned to take Stat 121 The number of students who got into their major of choice The number of students who were assigned to take Stat 121 Whether or not the student got into their major of choice
A study was done to determine whether or not taking Stat 121 will increase the chances of getting into one’s preferred major. 100 students participated in this study, 50 were randomly assigned to take Stat 121 and the other 50 did not take Stat 121. After the semester the students applied for their major choice and it was recorded whether or not the student got into the major.
The response variable is the variable being predicted or estimated. It changes as the result of changes to the explanatory variable. The value of the response variable depends on the other part of the experiment. In this case, the response variable is whether or not the student got into their major of choice because Whether or not the student got into their major of choice is affected by whether or not the student was assigned to take Stat 121.
An explanatory variable is known as the variable that is used to estimate the dependent variable. The explanatory variable is the variable that is expected to be causal to the dependent variable. In this case, the explanatory variable is whether or not the student was assigned to take Stat 121 because it is not affected by any other variable of the study.
