another version of Excel, you may need to research how to do the same steps.
Data in Excel
Excel is a powerful, yet user-friendly, data analysis software package. You can
launch Excel by finding the icon and double clicking on it. There are detailed
instructions on how to obtain the graphs and statistics you need for this lab in each
question. There is also a link to an Excel how to document on the iLab page where
you opened this file. Further, if you need more explanation of the Excel functions you
can do an internet search on the function like “Excel standard deviation” or “Excel
pivot table” for a variety of directions and video demonstrations.
Data have already been formatted and entered into an Excel worksheet. You will see
the link on the page with this lab document. The names of each variable from the
survey are in the first row of the worksheet. All other rows of the worksheet represent
certain students’ answers to the survey questions. Therefore, the rows are called
observations and the columns are called variables. Below, you will find a code sheet
that identifies the correspondence between the variable names and the survey
questions.
Survey Code Sheet: Do NOT answer these questions. The code sheet just lists the
variables name and the question used by the researchers on the survey instrument that
produced the data that are included in the Excel data file. This is just information. The
first question for the lab is after the code sheet.
Variable Name Question
