35, 50, 30, 40, 32, 43, 34, 41, 32, 33, 35, 50, 30, 40, 35, 43, 34, 41, 32,50
(a) Find the mode of this data.
(b) Is there more than one mode?

​

Answer 1

Mode = 32 , 35 , 50

There is more than one mode

Step-by-step explanation:

Given Data

Number of students = 20

There are weights are 35, 50, 30, 40, 32, 43, 34, 41, 32, 33, 35, 50, 30, 40, 35, 43, 34, 41, 32,50

___________________________

To Find

• Find the mode of this data

1. Is there more than one mode?

___________________________

We know that,

Mode = the number occurs

___________________________

Let's arrange the given data in ascending to descending order

30 , 30 , 32 , 32 , 32 , 33 , 34 , 34 , 35 , 35 , 35 , 40 , 40 , 41 , 41 , 43 , 43 , 50 , 50 , 50

___________________________

We know that,

Mode = the number occurs

Here,

32 , 35 , 50 all are occurred 3 times which is highest number of occurring in the given data

Mode = 32 , 35 , 50

___________________________

Here 3 numbers are occurring same that is 32 , 35 and 50

There is more than one mode
