4. What is the range of the values 2.0, 3.7, 4.9, 5.0, 5.7, 6.7, 8.5, and 9.0?
Answer: ________________________
What is the mean? _______________________
What is the median? ____________________
What is the mode?
A mean is the average of the all the numbers. You add all the numbers and divide by how many numbers you add together.
A median is the middle. Arrange the numbers from smallest to largest and find what number is in the middle.
A mode is whichever number that occurs/shown the most. For example, 2 2 3 5 6 8 8 8 9 10. The mode is 8 because it occurs the most frequently.
If there are two middle-most scores for the median, use the mean of those two scores.
Range is highest value minus lowest.
To find the range of a set of values, you need to subtract the smallest value from the largest value. In this case, the smallest value is 2.0 and the largest value is 9.0. So, the range is 9.0 - 2.0 = 7.0.
To find the mean, you need to add up all the values and divide the sum by the number of values. In this case, there are 8 values. So, you add up 2.0 + 3.7 + 4.9 + 5.0 + 5.7 + 6.7 + 8.5 + 9.0 = 45.5. Then, divide 45.5 by 8 to get the mean, which is 5.6875.
To find the median, you need to arrange the values in ascending order and find the middle value. In this case, the values in ascending order are 2.0, 3.7, 4.9, 5.0, 5.7, 6.7, 8.5, 9.0. Since there are 8 values, the middle value is the average of the 4th and 5th values, which are 5.0 and 5.7. So, the median is (5.0 + 5.7) / 2 = 5.35.
To find the mode, you need to identify the value(s) that occur(s) most frequently. In this case, none of the values occur more than once, so there is no mode.
Answer:
Range: 7.0
Mean: 5.6875
Median: 5.35
Mode: None
