Question

Here are the number of hours that 9 students spend on the computer on a typical day: 1 6 7 6 8 11 6 12 15 The data from the above 9 students form what type of distribution? Unimodal Ultimodal Bimodal

Answer 1

Answer:

Unimodal Distribution

Mode = 6        

Step-by-step explanation:

We are given the data of hours that 9 students spend on the computer on a typical day:

1, 6, 7, 6, 8, 11, 6, 12, 15

Sorted data: 1, 6, 6, 6, 7, 8, 11, 12, 15

Mode is the most frequent observation in the given data.

Here, 6 repeats itself most frequently that is 3 times. No other observation repeats itself three times.

Thus, the mode of the data is 6.

Since, there is a single mode for the given data, the distribution of students is unimodal.

Answer 2

Unimodal Distribution

Mode = 6        

• The calculation is as follows:

 

The sorted data is 1, 6, 6, 6, 7, 8, 11, 12, 15

Since 6 repeats 3 times so the mode should be 6

Also, there should be the single mode so the type of distribution is unimodal
