Answer:
Step-by-step explanation:
Mean: To find the mean add all the numbers together and divide the numbers by the number of numbers listed. Remember Round when Necessary!
1.) Add the numbers together! 2+5+7+1+9+13+10+8+7= 62
2.) DIvide 62 with the amount of numbers listed which is 9
Equation: 62/9
3.) The answer is 6.88888888889, but you would need to round to the nearest hundredth or tenth.
If rounded to nearest Hundredth: 6.89
Nearest Tenth: 6.9
Median: To find the median you would need to order the numbers smallest to greatest then find the middle number! Key concept: If there is an odd amount of numbers there should be a middle number! But if there is an even amount of numbers find the 2 middle numbers, add them together and divide by 2.
1.) Order the numbers LEAST TO GREATEST!
The order: 1,2,5,7,7,8,9,10,13
2.) Identify middle number *numbers if even amount!* (in this case there are 9 numbers for which you would need to identify one number!)
1,2,5,7,7,8,9,10,13 (Number in Bold should be the Median)
3.) Answer! 7 is the Median!
Therefore, The Mean of the data is 6.89 (rounded to the nearest hundredth) The Median is 7!
