SR = 1,8

 

terdapat 10 data

tentukan dulu

         5 + 4 + 9 + 8 + 9 + 7 + 8 + 4 + 10 + 6

x' = ----------------------------------------------

                                       10

        70

x' = ----

         10

x' = 7

 

sekarang tentukan Simpangan Rata-rata (SR)

           ∑ |5-7| + |4-7| + |9-7| + |8-7| + |9-7| + |7-7| + |8-7| + |4-7| + |10-7| + |6-7|

SR = ----------------------------------------------------------------------------------------

                                                                             10

           ∑ |-2| + |-3| + |2| + |1| + |2| + |0| + |1| + |-3| + |3| + |-1|

SR = ------------------------------------------------------------------

                                                        10

           2 + 3 + 2 + 1 + 2 + 0 + 1 + 3 + 3 + 1

SR = --------------------------------------------

                                      10

            18

SR = ------

             10

SR = 1,8

 

semoga membantu.
