Question

What is the mean, median, and mode?80.6, 60.8, 54.5, 61.4, 99.2, 71.1, 79.6, 79.8, 99.2,99.2

Answer 1

mean=78.54

median=79.7

mode=99.2

Step-by-step explanation

Step1

mean

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set

Let

sum of the data

`\begin{gathered} 80.6+60.8+54.5+61.4+99.2+71.1+79.6+79.8+99.2+99.2 \\ =785.4 \\ \end{gathered}`

and

number of data=10

so

Step 2

to find the median,

1)Arrange your numbers in numerical order.

2)Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Step 3

The mode is the value that appears most frequently in a data set

then, check for the value that most frequently appear is

`99.2(3\text{ times)}`

I hope this helps you
