Googleフォームによるアンケート調査で、複数の選択肢を選ぶことが可能な質問のデータを処理する方法。Transforming multiple response categories into a series of dummy variables using Google Form + Excel.

1. Transforming multiple
responses into a series of
dummy variables
Survey Methods

2. In Google Form, a “checkboxes” question allows
respondents to choose multiple response
categories.
The dataset will look like this.

3. To separate items (response categories), go to
DATA menu in Excel and choose “Text to
Columns.”
Click on Delimited.

4. Add Semicolon as Delimiter and voila!
The font color has been changed.

5. To more effectively analyze this data, we want the same fruit
(response category) to be in the same column. In the table below,
one could quickly and easily see that respondents #1 and #4 like
apples, but not respondents #2 and #3, etc.
One could
manually
manipulate the
data (sort, copy,
paste) to do this,
but it’s tedious.

6. There may be a number of solutions to this
problem. One is to use function COUNTIF.
Then look for COUNTIF.
Look in the cells B2, C2, D2, E2 and count
the number of times the word “Apples”
appear.

7. The answer is 1. This respondent likes
apples. 0 if s/he doesn’t like apples.

8. Do the same for the other three fruits.
Use absolute reference (“$”) if necessary. Make sure the range is constant (B, C, D, E)
F, G, H, and I columns contain dummy variables (1 if the
respondent likes the fruit, 0 if not). Then we can count the total
number of 1s. #1 and #2 both like two kinds of fruit. #4 likes all
four.

9. We don’t need the columns B, C, D, E any
more, do we? Let’s delete them.
No, they cannot be deleted because the COUNTIF (and SUM) data
depend on those original columns.
Options
-Hide the unwanted columns
-Copy and paste the values (using Paste Special). Then the COUNTIF
data are no longer dependent on the original data.
