Answer:
Mean: 9.6
Median: 7
Mode: 7
Range: 17
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
