Provide an appropriate response.Roughly speaking, the standard deviation indicates how far, on average, the observations are from the mean. Do you think that for the data set below the standard deviation will give a good indication of the typical deviation from the mean?2, 3, 4, 4, 5, 5, 6, 6, 100What drawback of the standard deviation is illustrated by this example?
What will be an ideal response?
Answers will vary. Possible answer: No, the standard deviation is 31.9. This is not a good indication of the typical deviation from the mean because the data set contains an extreme observation, namely 100. The standard deviation is very sensitive to extreme observations.
