This assignment is designed to give you a refresher on statistics. For this assignment, you are going to analyze some data using a t$-$test. You must download a copy of this assignment and fill in your answers on the document and submit it on Canvas.



To do this assignment, you$’$ll do the following:

$1.$ Download the CSV file from this module in Canvas called $“$Employee$\_$Satisfaction.csv$”$

$2.$ Import that data into JASP. If you can$’$t remember how to do that, watch the Downloading data in JASP video. REMEMBER: You will have to open the CSV file in either Excel or Google Sheets and delete the first three rows before uploading the file. The program will not work unless you do this.

$3.$ Perform the analysis necessary to answer the following questions about employee satisfaction and whether the employee ultimately left the company. You will use $“$satisfaction$\_$level$”$ as your dependent variable and $“$left$\_$company$”$ as your selection $($independent$)$ variable. The value of $1$ in $“$left company$”$ means yes, that employee did leave the company.
