What are the mean, median, mode, and range for this set of data? 5.1, 3.7, 3.1, 4.3, 7, 2, 4.3, 2.5

First, you need to rearrange the sequence in ascending order

2,2.5, 3.1,3.7,4.3,5.1,7.2

For mean, just use the formula and substitude the number into tge formula

Mean

= sum of the sequence / total sequence

= 27.9 / 7

= 3.99

For Median, You need to find the centre of the sequence that you've had rearrange just now. We can see that, 3.7 is the centre of the sequence.

Median = 3.7

For Mode, you just need to find the highest number in the sequence. Obviously the highest number is 7.2.

Mode = 7.2

For Range, you need to identify which one is the highest and the lowest number in the sequence. You've found the highest number just now. Now, you need to find out the lowest number. We can see that, the lowest number is 2. So, you just need to substract the highest and the lowest number. Take a look on the step below ...

Range = Highest number - Lowest number

= 7.2 - 2

= 5.2

Hope you enjoy!
