Question

When we compare mean and median, when do we use standard deviation to solve the problem and when do we use IQR.

Answer 1

Step-by-step explanation:When there are no outliers in a sample, the mean and standard deviation are used to summarize a typical value and the variability in the sample, respectively. When there are outliers in a sample, the median and interquartile range are used to summarize a typical value and the variability in the sample, respectively

Is it more appropriate to use the mean and standard deviation or the median and IQR to summarize theses data? Explain. It is more appropriate to use the median and IQR to summarize these data, because these data are not unimodal and symmetric.
