Question

complete the table below

class	frequency	xi	xifi	fx	xi-x	(xi-x)²	fi(xi-x)²
500-750	15
750-1000	23
1000-1250	55
1250-1500	92
1500-1750	65
1750-2000	50

find the mode, median, mean, variance, standard deviation and the coefficient of the variation

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
