1. One Variable

Before You Begin – Note the layout that StatKey requires: __#1. The first row contains the variable name __#2. Each data value is in its own row __#3. At the bottom, “Data has header row” is be checked



Illustration

One Variable (age) 44 16 37 Step 1 Launch Excel. Into Column A Row 1, enter the name of your variable (age). Next, beginning with Row 2, enter the values of your variable. Still in Excel, use FORMAT > CELLS to format the data in column A as text (for categorical variable) or as number, (for quantitative variable) as appropriate. When you are finished, your column A should look like the following:

Step 2 Still in Excel, select the data rows in Column A. From the menu bar, click EDIT > COPY (cntrl-C) Step 3 Launch StatKey. > From the main menu, under “Descriptive Statistics and Graphs”, choose One Quantitative or One Categorical > Click on the tab at top, Edit Data



> Delete the data that StatKey has supplied (so that you can insert yours here!)

> Paste your Excel Data (cntrl-V) and edit the data header. Check that: __i) “First column in identifier” is NOT checked __ii) “Data has header row” is checked.

> Click OK



2. One Categorical and One Quantitative Variable

Before You Begin – Note the layout that StatKey requires: __#1. The first row contains the variable names, separated by a comma, in order: categorical, quantitative __#2. Each data value is in its own row __#3. At the bottom, “Data has header row” is checked

One Categorical (gender) and One Quantitative (age) Male, 44 Male, 16 Female, 37 Step 1 Launch Excel. Into Column A Row 1, enter the name of your first, categorical, variable (gender). Next, beginning with Row 2, enter the values of your variable. Still in Excel, use FORMAT > CELLS to format the data in column A as text. When you are finished, your column A should look like the following:

Step 2 Into Column B Row 1, enter the name of your second, quantitative, variable (age). Next, beginning with Row 2, enter the values of your variable. Still in Excel, use FORMAT > CELLS to format the data in column B as number. Choose decimal places: 2 When you are finished, your column B should look like the following:



Step 3 Concatenate. Now position your cursor in COLUMN C, row 2. Into the formula box, type = concatenate(A2,”,”,B2) You should now see in Column C, row 1:

Step 4 Using EDIT > COPY > PASTE, repeat for the remaining rows of data. You should now see in Column C:

Step 5 Copy. Still in Excel, select the data rows in Column C ONLY, beginning with ROW 2. From the menu bar, click EDIT > COPY (cntrl-C)



Step 6 Launch StatKey. > From the main menu, under “Descriptive Statistics and Graphs”, choose One Quantitative and One Categorical > Click on the tab at top, Edit Data

Next, beginning with Row 2, enter the values of your variable. Still in Excel, use FORMAT > CELLS to format the data in column B as number. Choose decimal places: 0 When you are finished, your column A should look like the following:

Step 2 Into Column B Row 1, enter the name of your second, quantitative, variable (weight). Next, beginning with Row 2, enter the values of your variable. Still in Excel, use FORMAT > CELLS to format the data in column B as number. Choose decimal places: 2 When you are finished, your column B should look like the following:



Step 3 Concatenate. Now position your cursor in COLUMN C, row 2. Into the formula box, type = concatenate(A2,”,”,B2) You should now see in Column C, row 1:

Step 4 Using EDIT > COPY > PASTE, repeat for the remaining rows of data. You should now see in Column C:

Step 5 Copy. Still in Excel, select the data rows in Column C ONLY, beginning with ROW 2. From the menu bar, click EDIT > COPY (cntrl-C)



Step 6 Launch StatKey. > From the main menu, under “Descriptive Statistics and Graphs”, choose Two Quantitative Variables > Click on the tab at top, Edit Data

> Delete the data that StatKey has supplied. TIP – This time around KEEP the data header (which you will edit later)
