4. Определение межквартильного размаха

 

_{Q1 – меньшая квартиль, Q1 = n + 1  =   7 + 1     =  2}                                                                                                         

                                                    _{4                      4}              

 

_{Q3 – большая квартиль, Q3 =  3(n + 1) =  3(7 + 1)  =  6}

                                                        _{4                4}    

 

IQR – межквартильный размах 

 

IQR = Q₃ – Q₁ = 6 – 2 = 4

5. Определение среднего квадратичного отклонения

 

S = ^{Ö S(х_i – х)2}

            ^{Ö n}

^{n = 7}

^{х₁₉₉₃ = 0 + 2 + 9 + 11 + 14 + 9 + 7 =  52 = 7,43}

6. ^{Определение дисперсии}

 

^{D₁₉₉₃ = S2 = 4,92 = 24,01                        D₁₉₉₅ = S2 = 7,12 = 50,41}

 

 

7. ^{Определение коэффициента вариации}

 

V₁₉₉₃ =  S * 100% = 4,9 * 100% = 65,9%

                   x                  7,43                                              

 

 

V₁₉₉₅ =  S * 100%  =   7,1 * 100% = 95,6%         

                   x                    7,43

 

 

8. Определение показателя асимметрии

 

A₁₉₉₃ = x – M = 7,43 – 9,7 =  -0,463

               S              4,9                    

 

A₁₉₉₅ = 7,43 – 9,3 =  -0,263
