REVIEW OF MEAN, MEDIAN, MODE RANGE, BOX PLOTS, DOT PLOTS AND HISTOGRAMS WARM UP Find the linear equation that passes through the following points: (3,4) (5,8) OBJECTIVE The student will be able to find the mean, median, mode and range of a set of data and create a box and whisker, histogram and dot plot. TRY WITH A PARTNER Find the Mean, Median, Mode, and Range of the following set of data: 80, 81, 79, 100, 87, 91, 99, 100, 95, 92, 93, 97 FINDING MEAN, MEDIAN, MODE AND RANGE Mean: is the average of a set of data Median: is the middle number after ordering the data from least to greatest. Mode: Is the most common number in a set of data. Range: How “far” the data spreads. CONTINUED… Find the Mean, Median, Mode and Range of the following: 10, 9, 7, 10, 8, 6, 5, 9, 9 WITH A PARTNER Create a Histogram with the following set of data: 25 15 28 52 22 38 42 44 24 32 19 28 29 20 31 HISTOGRAMS Are Similar to Bar Graphs but have a few important differences: They do not have gaps between sets of data Data on the x-axis is grouped into ranges. The y-axis represents frequency the data on the x- axis appears CONTINUED CONTINUED WITH A PARTNER Create a Dot Plot with the following data: DOT PLOTS Dot Plots graphically represent data frequency using dots or x’s. x-axis: shows categories of data y-axis: shows frequency. CONTINUED WITH A PARTNER Create a Box and Whisker Plot from the following data: 12, 9, 10, 15, 19, 20, 17, 19, 14, 19 BOX AND WHISKER PLOTS Vocabulary: Quartile: one fourth or one quarter of the data. Extreme: the value that is far from the rest of the data. The largest and smallest value. CONTINUED CONTINUED Steps to make a Box and Whisker: Order and organize the data. Find the extremes. Find the median. Find the quartiles. Use the information to create the plot. EXIT TICKET AND HOMEWORK Exit Ticket: Find the mean, median, mode and range of the following: 10, 10, 3, 4, 5, 7, 9 Homework: Worksheet.
