In a current study, we try to define the idea of smartphone addiction and smartphone usage and how these ideas differ in terms of gender, economic status and how often an individual uses a smartphone. A survey is developed, which includes 12 questions.


First, find out what smartphone addiction and smartphone usage are, how the two-factor model looks like? Make sure you include all the variables. (smartphone addiction and smartphone usage are independent, and we already know that smartphone addiction can explain more variance) Write a summary to report your findings with table and model.)


Second, test your final model to confirm it is a good model. Write a summary to report your findings.


What is the difference between gender (male: 1, Female: 2), after controlling for age, in terms of their smartphone usage? Perform an appropriate test and write a summary.


If we would like to use smartphone addiction and smartphone usage, to predict how often an individual uses a smartphone (Frequency: on average, how many hours do you use your phone every day), what should we do? Perform an appropriate test and write a summary.
