3 Learning Targets For a given set of data: LT # 3: I can find the mean. LT #4: I can find the median.LT #5: I can find mode.LT #6: I can find the range.LT #7: I can find the outlier and determine its effect on the mean.LT #8: I can find the minimum and maximum of a data set.
4 For Learning to Happen! Calcs okay for math practice/homework, Take out a calculator.Be sure you have a whiteboard and penCalcs okay for math practice/homework,but NOT on the test.
5 6 + 9 = 15 Vocabulary Review Sum – the answer to an addition problem. Addend – the numbers you add together to get the sum.6 + 9 = 15
37 LT # 3 - 6 Measures of Central Tendency Mean - the average. Add the values and divide by the number of the numbers.Median - the middle number. All the numbers must be in order.Mode - the most common number. The number you see the most.Range - the largest number minus the smallest number.
38 LT # 7OUTLIERAn outlier is a number that is much higher or much lower than the other numbers.3, 9, 4, 36, 8, 7, 31) What is the outlier?36707 =102) Find the mean of all the numbers346 = 5.63) Find the mean without the outlier.4) How did the outlier affect the mean?The outlier increased the mean
39 Minimum & Maximum #8 The minimum of a data set is the lowest value. The maximum of a data set is the highest value.Find the minimum and maximum of the following data set:5, 6, 7, 7, 7, 8, 9, 11, 14, 16, 19, 22MinimumMaximum
