Document Summary

If there"s more than one mode, it"s bimodal, and if there"s multiple, then it"s multimodal. Guideline that is used to state the approximate percentage of values that lie within a given number of standard deviations from the mean of a set of data if the data are normally distributed. Learning objective three: compute the mean, median, mode, sd, and. Group data doesn"t give information about individual values so measures of central tendency have to be calculated differently : mean for grouped data i = number of classes. 4: measures of variability for grouped data. Learning objective four: describe a data distribution statistically and. It can be left skewed or right skewed: relationship with skewness and the mean, median, mode: 5: left skewed, mean < median < mode, right skewed, mean > median > mode, coefficient of skewness, this compares the mean and median in light of the magnitude of the.
