Data Analysis
Please look at the information below and answer these questions

1 What are the variables in the datasets and their levels of measurement?
2 Write a section on the properties of the sample, using typical descriptive statics, as
appropriate (e.g., mean and standard deviation, median when appropriate, skewness
and/or normality, frequencies, etc.). Use a format similar to the way descriptive
statistics are reported in research papers. Cite the research paper or papers you relied
on when constructing this section.
3 In the scatterplot of income (on the y-axis) as a function of “years in the current job” Is
there an association between these two variables?
Using the variables in the dataset, please construct a theory which involves an IV, DV, a
mediator and a moderator. You may add imaginary variables as you wish (e.g., a new
variable which does not exist in the dataset as a moderator or a DV). Explain your theory.
