Answer:
15, 89, 86, 86
Step-by-step explanation:
To find the range of any data, follow the steps
Step-1: Arrange the set of data in ascending order.
Step-2: Divide the smallest value from highest value. Means, highest value - smallest value.
= 79, 83, 84, 86, 86, 90, 94
= 94 - 79
= <u>15</u>
To find the mean of any data, follow the steps
Step-1: Add all the numbers.
Step-2: Divide the result by the numbers of observation.
= (79 + 83 + 94 + 86 + 90 + 84 + 86) ÷ 7
Here, we divide it by 7 because, there are 7 numbers in the data.
= 602 ÷ 7
= <u>86</u>
To find the median of any data, follow the steps
Step-1: Arrange the numbers(given in data) in ascending order.
Step-2: Find the middle number in the set.
= 79, 83, 84, 86, 86, 90, 94
Now, find tee middle number in it.
= <u>86</u>
See in last, to know, what will be the median, if there will be 2 numbers in the middle.
To find the mode in any data, see that which number is occurring the most.
In this set of data, 86 is occurring the most number of times from others.
= 86
Mode can be more than 1 in a set of data. So, don't get confused that what will be the mode, if you find more than 1 mode in a set of data.
what will be the median, if there will be 2 numbers in the middle?
There will be only 1 median in a set of data.
To know the median if there are two numbers in the middle, just remember the steps which is written down.
Step-1: Add both the middle numbers.
Step-2: Divide the result you get after adding.
For example, to find the median in 79, 83, 94, 86, 90 and 84.
First we need to arrange them in ascending order.
After arranging them in ascending order we will get the result, 79, 83, 84, 86, 94, 90.
So, here there are two numbers in the middle that are 84 and 86.
So, add them and divide it by 2.
= (84 + 86) ÷ 2
= 170 ÷ 2
= <u>85</u> is our final answer.
Hope, now you know how to find median if there are two numbers in middle.
