How can a stem and leaf plot be used to determine the mode of a data set?
The mode of a data set is simply the most frequently occurring value. The mode can be determined from a stem and leaf plot using what one eminent statistician refers to as the "inter-ocular traumatic test" (i.e. by looking at it!)For example, take the following data set:10, 11, 20, 21, 24, 27, 27, 27, 28, 28, 29, 29, 29, 31, 33, 33, 33, 33, 33, 39, 531|012|014777889993|13333394|5|3Even though the peak corresponds with the 20s cohort, it's clear that the most frequently occurring value, and hence the mode, is 33.
If 6 cards are drawn at random from a standard deck find the probability that all the cards are hearts?
(13/52)*(12/51)*(11/50)*(10/49)*(9/48)*(8/47)=33/391510, which is approximately .0000842 .
