Find the mean, median, mode, and range of the data set 19, 7, 16, 2, 10, 6, 7. If necessary, round our answers to the nearest tenth.

Mean: 9.6

Median: 7

Mode: 7

Range: 17

Step-by-step Explanation:

Mean: add all the numbers then divide the sum by how many numbers there are

19 + 7 + 16 + 2 + 10 + 6 + 7 = 67

67 / 7 = 9.57 --> 9.6

Median: arrange your numbers in numerical order, count how many numbers you have (if odd, divide by 2 and round up to the position of a median number, if even, divide by 2 and go to that number in position)

2, 6, 7, 7, 10, 16, 19 (7 numbers = since its odd, divide by 2 which equals 3.5, round it up to 4 and go to the number in the 4th position, in this case 7)

Mode: Put the number in order again and determine which number appears the most

2, 6, 7, 7, 10, 16, 19  = 7 appears twice while the rest only appears once

Range: subtract the lowest value from the highest value

19 - 2 = 17

Step-by-step explanation:

19, 7, 16, 2, 10, 6, 7

In ascending order:

2,6,7,7,10,16,19

mean:

(2+6+7+7+10+16+19)/7

=67/7

=9.6

Median:  7

Mode: 7

Range:

19 - 2 = 17

the answer is  

a.
