Name Period Date7.2 Notes – Box-and-Whisker PlotsI CAN create a box and whisker plotI CAN interpret a box and whisker ---------------------------A boxand whisker plot is a data display that organizes data values into groups.INTERPRETING Box and Whisker Plots - A box and whisker plot separates data into FOURsections The two parts of the box and two whiskers. All four sections contain about the samenumber of data values.The lengths of the sections tell you how spread out the data are.Definitions:Lower Quartile - The of the lower halfUpper Quartile - The MEDIAN of the halfLower Extreme - The data valueUpper Extreme - The greatest valueSteps for creating a box and whisker plot:1. Order your data from least to greatest2. Find the median of your data3. Find the quartiles of your data (the median of the upper and lower half)4. Find the extremes of your data (the least and greatest values)5. Plot the median, quartiles, and extremes below a number line (USE A RULER TO MAKE SURE YOUR NUMBERLINE “TICK MARKS” ARE EVENLY SPACED!!)6. Draw the box and the whiskersWhen a data set has an odd number of values, do NOT include themedian in either half of the data when determining the quartiles.

The box-and-whisker plots show the weights of electric handheld power blowers andgasoline handheld power blowers.a) Compare the median, range, and interquartile range for the two types of blowers
Continued from #2 on front.b) About what percent of electric blowers are less than 7.5 pounds?c) About what percent of gasoline blowers are more than 10.5 pounds?d) Which type of blower would you say is the “lighter” blower? Explain.3. Usethe following information: An outlier is a data value whose distancefrom the upper or lower quartile is more than 1.5 times the interquartilerange.a) Make a box-and-whisker plot for the following data (snowfall, in inches, of the topten snowiest cities in the U.S. in a recent year): 100, 129, 105, 97, 112, 103, 156, 110,117, 98b) Determine if there are any outliers in the snowfall data set. Explain how you know.
Explain what the box and whisker plot says. See the last example on your notes if you are stuck. You shouldhave AT LEAST 4 bullet points to say about this.

A box and whisker plot is a way of showing and comparing distributions. The box represents the middle half of the data (from the 25th to the 75th percentile), . often these give a better idea of the distribution of the data than the minimum and maximum. Box plots can be drawn vertically or horizontally. Box and Whisker charts in Excel

Mental health in primary care A briefing for Clinical Commissioning Groups 5 One in four of us will experience a mental health problem in any given year, but most of us don’t get professional help. Of those of us who do get treatment, the majority are treated within primary care.10 This is why good mental health support in primary care is so important. Local GPs and other primary care staff .
