Find the geometric mean of the pair of numbers 99 and 11. a) 968. b) 33. c) 43. d) 38

Geometric Mean = √ (99 · 11) = √( 9 · 11 · 11 ) = 
= √(3² · 11²) = 3 · 11 = 33
B ) 33 

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
