Statistics D1 Mean, Median, Mode, and Range

2
D1 Mean, Median, Mode, & Range Mean (average) - _______ all the values then ________ by the number of values Add divide Median (middle) - Put the values in ______ and pick the ________ number (If there are two middle numbers, the median is their __________) order middle average Mode (most) – There can be ___ or ______ modes. There can also be _____ modes The number that appears the most 1more no

3
D1 Mean, Median, Mode, & Range Range (difference in values) –__________ the smallest value from the biggest value subtract From the smallest to the biggest

Example A.Which statement is true about the data set 10, 14, 19, 19, 43, 44? (1) mean = mode (2) mode = median (3) mean < median (4) mode > range First we need to find the mean, median, mode, & range before we can answer the question Average Add up the numbers 10 + 14 + 19 + 19 + 43 + 44 Mean = 149 Divide by the number of values 123456 ÷6=24.8333… Round to the hundredth place 24.83

Example A.Which statement is true about the data set 10, 14, 19, 19, 43, 44? (1) mean = mode (2) mode = median (3) mean < median (4) mode > range First we need to find the mean, median, mode, & range before we can answer the question 10 + 14 + 19 + 19 + 43 + 44 Mean = 149÷6=24.83 Median = Middle number Make sure the data is in order from smallest to biggest What is the average of 19 and 19? 19

(1) mean = mode (2) mode = median (3) mean < median (4) mode > range First we need to find the mean, median, mode, & range before we can answer the question 10 + 14 + 19 + 19 + 43 + 44 Mean = 149÷6=24.83 Median =19 Mode = The number that appears the most 19

(1) mean = mode (2) mode = median (3) mean < median (4) mode > range First we need to find the mean, median, mode, & range before we can answer the question 10 + 14 + 19 + 19 + 43 + 44 Mean = 149÷6=24.83 Median =19 Mode =19 Range = The difference between the biggest and smallest numbers 44–10=34

Example A.Which statement is true about the data set 10, 14, 19, 19, 43, 44? (1) mean = mode (2) mode = median (3) mean < median (4) mode > range 10 + 14 + 19 + 19 + 43 + 44 Mean = 149÷6=24.83 Median =19 Mode =19 Range =34 Now, we can answer the question X Let’s just check the others X X
