The document discusses detecting unengaged responses in survey data. It focuses on identifying responses where participants were not paying attention by calculating the standard deviation of responses. Standard deviation measures how spread out the data is - a lower standard deviation indicates responses are closer to the mean, suggesting lack of attention. The document recommends calculating standard deviation to find unengaged responses that are not meaningful for analysis. A related video provides more information on detecting unengaged responses.

Why to calculate Standard Deviation (SD)?
• Standard deviation measures the spread of a data
distribution.
• The more spread out a data distribution is, the greater its
standard deviation.
• SD is a special form of average deviation from the
mean.

• A standard deviation close to 000 indicates that the data
points tend to be close to the mean (shown by the red line).
