To find the mean= add all numbers then divide by the amount of numbers there are
25/5=5
So, mean=5
To find the median- order the numbers from least to greatest, then look for the middle number.
2, 5, 5, 6, 7
The middle number is 5, so the median is 5.
To find the mode, look for the most commonly used number. 5 is used twice, which is the most, so 5 is the mode.
To find the range, subtract the smallest number from the largest number.
7-2=5
So, the range is 5.
In summary:
Mean: 5
Median: 5
Mode: 5
Range: 5
