A researcher has reported the standard deviation of a data set. What might be the reason they chose this measure of variability? When plotted, the data had a large distribution Oa. Ob. When plotted, the data set had one number that was more frequent than the others. When plotted, the data set was skewed Od When plotted, the data set had a normal distribution
