Question

Determine The mean,median,mode, and range for each data set A. {2,2,7,9,10}​

Answer 1

Answer:

Step-by-step explanation:

Median:

2,2,7,9,10 - you have to always find the number on the middle. But if there is 2 numbers remaining, you have to add both of them and divide by 2. So the median here is: 7.

Mode:

2,2,7,9,10 - to find the mode you need to see what number repeats itself more. So the mode here is: 2.

Range:

2,2,7,9,10 - to find the range you need to put the numbers in order and subtract the smallest number from the highest number. So the range here is 10 - 2 = 8 .

Mean:

2,2,7,9,10 - to find the mean you need to add up all of the answers and then you need to divide that answer by how many numbers there are. So the mean here is: 2+2+7+9+10 = 30

             30 divided by 5 (how many numbers there are) = 6

sorry if i took long:)

Answer 2

Answer:

Mean: 6, Median: 7, Mode: 2, Range: 8

Step-by-step explanation:

Mean:

The mean is the average of the data set.

Add all the terms together:

$2+2+7+9+10=\\4+7+9+10=\\11+9+10=\\20+10=\\\boxed{30}$

Divide the sums by the number of terms:

There are 5 terms in the data set.

$30/5=6$

The mean is 6.

Median:

The median is the middle value of the data set.

The data set given already has the numbers in ascending order.

Seven appears to be in the middle of the set.

{2,2,7,9,10}​

The median is 7.

Mode:

The mode is the number that appears the most in a data set.

The number two appears twice in the data set, and all other numbers (7, 9, and 10) appear once.

The mode is 2.

Range:

The range is the difference between the largest data value in the set and the smallest data value in the set.

In the given set, 10 is the biggest and 2 is the smallest.

10 - 2 = 8

The range is 8.
