Mean Median Mode And Range Worksheet

                    Lesson 1

 

                                                            Problem:       Calculate the mean,  median,  mode and range for the data set.

                                                                                     Data Set: 2, 7, 8, 4, 7, 2, 5, 31, 14, 31 ,22

 

                                                            Solution        The range is lowest value (2) and highest value (31) in the set.

                                            Step 1:            So the range is (2-31).                                                                                         

                           

                                                            Solution         Mean = (Total of all observations) / # of observations.

                                                            Step 2:             So the mean = (2+7+8+4+7+2+5+31+14+31+22)/11 = 12.1  

 

Step 3:
Median is the value of observation which divides the data distribution equal half of into two parts. Half of the observations are above it and half of observations are below it.

                                                                                                                                                                                                  

                                                                      So the median is 9/2= 4.5                  

 

                                                            Solution          Mode is that value which occurs most often.

                                            Step 4:               2 appear the most.                           

 

                                                             Solution          Mean = 12.1  Median = 4.5            Mode = 2       Range = 2-31

                         

 

                         Try two practice problems:  

                                            

1.    Calculate the mean,  median,  mode and range for the data set.

        Data Set: 2, 5, 6, 3, 8, 4,5, 6, 10, 4, 3 ,

 

2.    Calculate the mean,  median,  mode and range for the data   set.

         Data Set: 2, 5, 2, 7, 4, 2, 8, 12, 5, 4,10,11
