Question 1 of 8
1. Question
Find the range
7 9 12 14 4 7 2 13 18 6 - Range = (16)
Correct
Keep Going!
Incorrect
Range Formula
Highest Score−Lowest ScoreRemember
The range of a data set is simply the difference between the largest and smallest values.First, find the highest and the lowest score.Highest Score = 18 Lowest Score = 2 Finally, subtract the lowest score from the highest score to get the rangeRange = Highest Score−Lowest Score Finding the range = 18−2 Substitute values = 16 Evaluate Range=16 -

The range of a data set is simply the difference between the largest and smallest values.First, find the highest and the lowest score.Highest Score = 27 Lowest Score = 2 Finally, subtract the lowest score from the highest score to get the rangeRange = Highest Score−Lowest Score Finding the range = 27−2 Substitute values = 25 Evaluate Range=25 -
Question 3 of 8
3. Question
Find the mean50 51 53 44 49 52 49 51 51 50 56 48 32 50 53 42 Round your answer to two decimal places- Mean = (48.81)
Correct
Great Work!
Incorrect
Mean Formula
Mean=∑xNRemember
∑x is the sum of all the given values.N is the number of given values.First, solve for the sum of the given values.∑x = 50+51+53+44+49+52+49+51+51 +50+56+48+32+50+53+42 = 781 Next, divide the sum of all values (∑x) by the number of values (N).Mean = ∑xN Finding the mean = 78116 There are 16 given values = 48.81 Rounded to two decimal places Mean=48.81 -

Question 6 of 8
6. Question
Find the mode59.6 5.6 36.2 61.6 66.4 66.6 55.4 47.8 61.4 43.8 16 48.2 15.2 14.4 54.6 47.8 37.6 26.8 32.4 62.8 67.8 47.4 46.6 - Mode = (47.8)
Correct
Excellent!
Incorrect
The mode of a data set is the value with the highest frequencyWe need to identify the value that appeared most from the data set.59.6 5.6 36.2 61.6 66.4 66.6 55.4 47.8 61.4 43.8 16 48.2 15.2 14.4 54.6 47.8 37.6 26.8 32.4 62.8 67.8 47.4 46.6 We can see that the value 47.8 occured twice, and is the most frequent value of the data set.Therefore, the mode for this data set is 47.8Mode=47.8 -

8. Question
Find the median7.75 9.25 6.25 5.75 7.25 5.5 6 7 6.75 7 7 6.5 6.5 5.5 7 8 6 6.75 7.75 7.5 7 6 - Median = (6.875)
Correct
Excellent!
Incorrect
The median is the middle value of a data set.If there are two middle values on a data set, we get their sum and halve it to get the median.First, arrange the values of the data set in ascending order5.5 5.5 5.75 6 6 6 6.25 6.5 6.5 6.75 6.75 7 7 7 7 7 7.25 7.5 7.75 7.75 8 9.25 We can see that the values 6.75 and 7 are the middle values of the data set.To find the median, we add the two middle values and divide it by 2Median = 6.75+72 = 13.752 = 6.875 Median=6.875
