6,12,6,8,10,12,8,14,16 find mean medion mode and standerd deviation

Answer 1

Mode = most frequently occurring score(s)

Median = arrange in order of value, then find middle-most score.

Mean = sum of scores/number of scores

Subtract each of the scores from the mean and square each difference. Find the sum of these squares. Divide that by the number of scores to get variance.

Standard deviation = square root of variance

I'll let you do the calculations.

Answer 2

Arrange the collection data values in order with their corresponding frequently: 2 6 5 8 5 5 3
1. What score frequently appears?
2. What score appears to be in the middle?
3. How many students fall below the middle?

Answer 3

Arrange the collection data values in ascending order with their corresponding frequently: 2 6 5 8 2 5 5 3
Questions:
1. What score frequently appears?
2. What score appears to be the middle?
3. How many students fall below the middle score?
