21.a measure that describes how spread out or scattered a set of data (3 Words)
22.data values are evenly distributed on both sides of the mean (2 Words)

25.each of the 100 equal groups into which a population can be divided according to the distribution of values of a particular variable
26.tells how many standard deviations a data value is above or below the mean for a specific distribution of values (2 Words)
27.a rough estimate of the middle, the sum of the lowest value and the highest value divided by two
29.each of ten equal groups into which a population can be divided according to the distribution of values of a particular variable
30.an approximation or rough estimate of the standard deviation, range divided by 4 (4 Words)
31.statistical measures relatively unaffected by outliers within a data set; e.g., median and quartiles. (2 Words)
32.the midpoint of data array, number physically in the middle
33.the mode for grouped data, the class with the largest frequency (2 Words)

17.specifies the proportions of the spread of the data in terms of the standard deviation (2 Words)
19.a measure of how spread out numbers are, the square root of the variance (2 Words)
24.area of variation between upper and lower limits on a particular scale, highest value minus lowest value
28.a data set with two values that occur with the same frequency
