2.0,3.7,4.9,5.0,5.7,6.7,8.5,and 9.0

what is the range?
median?
mean?
mode?

Range = highest score - lowest

Mode is most frequently occurring score.

Mean = sum of score values divided by number of scores.

Median = point where 50% of scores have higher value and 50% have a lower value. (Make sure the scores are arranged in order of value.) Where you have two middle-most scores, it is the mean of those two scores.

You can do the calculations.

What is the range of the values 2.0, 3.7, 4.9, 5.0, 5.7, 6.7, 8.5, and 9.0?

To find the range, median, mean, and mode for the given set of numbers (2.0, 3.7, 4.9, 5.0, 5.7, 6.7, 8.5, and 9.0), follow these steps:

1. Range: The range is the difference between the highest and lowest values in the set. To find the range, subtract the lowest value from the highest value. In this case, the lowest value is 2.0 and the highest value is 9.0. Therefore, the range is 9.0 - 2.0 = 7.0.

2. Median: The median is the middle value in a set of numbers when they are arranged in numerical order. Start by arranging the numbers in ascending order: 2.0, 3.7, 4.9, 5.0, 5.7, 6.7, 8.5, 9.0. Since there are eight numbers in this set, the middle two numbers would be 5.0 and 5.7. To find the median, calculate the average of these two values. (5.0 + 5.7) / 2 = 5.35. Therefore, the median is 5.35.

3. Mean: The mean (also known as the average) is calculated by adding up all the values in a set and then dividing the sum by the number of values. Add up all the given values: 2.0 + 3.7 + 4.9 + 5.0 + 5.7 + 6.7 + 8.5 + 9.0 = 45.5. Since there are eight numbers in the set, divide the sum by 8: 45.5 / 8 = 5.6875. Therefore, the mean is 5.6875.

4. Mode: The mode is the value(s) that appear most frequently in a set of numbers. In this case, none of the numbers appear more than once, so there is no mode.

In summary:
- Range: 7.0
- Median: 5.35
- Mean: 5.6875
- Mode: None
