A: c) No, here based one mean, median and mode values we could see the data was skewed, so the median…

Q: Why do you think that the mean is the most sensitive measure of central tendency?

A: We know that, mean is the ratio of sum of all observation and number of observation. Let, xi be the…

Q: Why is the median less affected by skewed data than the mean?

A: Mean: The average values of the total observations. Median: The value that divided data set into two…

Q: Is there any skewness suggested by the mean, mode and median of the ungrouped data?

A: Skewness means lack of symmetry. The values of mean, median and mode fall at different points, they…
