Shown here are four frequency distributions. Each is incorrectly constructed. State the reason why.

Shown here are four frequency distributions Each is incorrectly constructed State the reason why class=

Respuesta :

Answer/Step-by-step explanation:

a. The the class width for the 1st, 2nd, 3rd, and 5th row equal 5 in the frequency distribution. Whereas, in the 4th row, the class width is 4 (49 - 45). This makes the construction incorrect.

b. Here, the upper limit of each consecutive class was used as the lower limit if the next class. For example, 9 is a member of the first class, which is the upper limit if the class in the first row, it ought not to be included as a member of the next class in the second row.

c. In the 3rd row, the lower limit of the class should be 133, NOT 138.

d. Different class width were used.

Row 1 class width = 13 - 9 = 4

Row 2 class width = 19 - 14 = 5

Row 3 class width = 25 - 20 = 5

Row 4 class width = 28 - 26 = 2

Row 5 class width = 32 - 29 = 3

The reason for all the frequency distribution is given below and this can be determined by using the given data.

Check all the options in order to determine the reason for the incorrect construction.

A) The given frequency table is given below:

Class            Frequency          

27-32                 1                                

33-38                 0                              

39-44                 6                              

45-49                 4                              

50-55                 2                              

In the fourth row, the class should be ending with 50.

B) The given frequency table is given below:

Class            Frequency          

5-9                     1                                

9-13                    2                              

13-17                   5                              

17-20                  6                              

20-24                 3    

                   

In the fourth row, the class should be ending with 21.

C) The given frequency table is given below:

Class            Frequency          

123-127                 3                                

128-132                 7                              

138-142                 2                              

143-147                 19                              

                   

In the second row, the class should be starting from 127.

D) The given frequency table is given below:

Class            Frequency          

9-13                     1                                

14-19                    6                              

20-25                  2                              

26-28                  5                              

29-32                  9  

                   

In the second row, the class should be starting from 13.
