Range Formula
Highest ScoreHighest Score-−Lowest ScoreLowest 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 ScoreHighest Score == 1818 Lowest ScoreLowest Score == 22 Finally, subtract the lowest score from the highest score to get the rangeRangeRange == Highest ScoreHighest Score-−Lowest ScoreLowest Score Finding the range == 1818-−22 Substitute values == 1616 Evaluate Range=16Range=16 -

Mean Formula
Mean=∑xNMean=∑xNRemember
∑x∑x is the sum of all the given values.NN is the number of given values.First, solve for the sum of the given values.∑x∑x == 50+51+53+44+49+52+49+51+5150+51+53+44+49+52+49+51+51 +50+56+48+32+50+53+42+50+56+48+32+50+53+42 == 781781 Next, divide the sum of all values (∑x)(∑x) by the number of values (NN).MeanMean == ∑xN∑xN Finding the mean == 7811678116 There are 1616 given values == 48.8148.81 Rounded to two decimal places Mean=48.81Mean=48.81 -

6. Question
Find the mode59.659.6 5.65.6 36.236.2 61.661.6 66.466.4 66.666.6 55.455.4 47.847.8 61.461.4 43.843.8 1616 48.248.2 15.215.2 14.414.4 54.654.6 47.847.8 37.637.6 26.826.8 32.432.4 62.862.8 67.867.8 47.447.4 46.646.6 - Mode =Mode = (47.8)
Correct
Excellent!

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.59.659.6 5.65.6 36.236.2 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 -

Range Formula
Highest Score-Lowest ScoreRemember

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
