Who’s the Best? Take out your WS: Who’s the Best? Review answers with you group. Take a position: Who do you think is the best player?

Warm Up Do not talk to your partners! Calculate the measures of central tendency and spread for this data:

Warm Up for 7/25 Solve these: 1. 1/5 + 2/5 = 2. 3/8 – 1/8 = 3. ½ + 1/3 =

Five Number Summary The FIVE NUMBER SUMMARY is: Lower Extreme or Minimum Lower quartile (Q 1 ) Median (Q 2 ) Upper quartile (Q 3 ) Maximum

Five Number Summary Lower Extreme or Minimum The smallest piece of data in a set Upper Extreme or Maximum The largest piece of data in a set. Median (Q 2 ) The middle piece of data in a set when the data are in order. Lower quartile (Q 1 ) The median of the lower half of the data Upper quartile (Q 3 ) The median of the upper half of the data Quartiles split a data set into four equal subsets

Five Number Summary Split this data in half Now, split it into fourths. These values become the FIVE NUMBER SUMMARY of the data.

5 Number Summary Find the five number summary of this data

Group Work: Finding 5 Number Summaries As a group, complete WS: 2-4 Enrichment

Warm Up for 7/28 Find the five number summary to this data:

Creating a Boxplot

Boxplots Box-and-whisker plots, or boxplots, are a visual five number summary. Min. Q 1 Med.Q 3 Max. Minimum LowerMedian Upper Maximum Quartile Quartile

Boxplots Box-and-whisker plots, or boxplots, are a visual five number summary. Min. Q 1 Med.Q 3 Max. Minimum LowerMedian Upper Maximum Quartile Quartile Lowest 25% of data Middle 50% of data Highest 25% of data

Warm Up for 7/ What is the five number summary of this data? (Hint – don’t read the number line, read the boxplot!)

Group Work for 7/29 Make a box and whisker plot of the data. Answer the following: 1. The middle 50% of the fat data are between which two numbers? 2. List two numbers that represent 25% of the data. Bacon9 Beefsteak15 Bologna16 Crabmeat3 Fish Sticks3 Fried Shrimp10 Ground Beef18 Ham14 Pork Chop19 Roast Beef5 Salmon5 Sardines9 Trout9 Tuna7 The grams of fat per serving of meats are shown in the table.

Warm Up for 7/ What part of the boxplot represents the middle 50% of the data? 2. What percent of the data is between 34 & 54? 3. Does a boxplot display measures of center, measures of spread, or both?

Interquartile Range (IQR) What is the range of this data? How is that shown on the boxplot? What percent of the data is between the Q1 and Q3? What is the distance between the Q 1 and Q 3 ? This is called Interquartile Range (IQR).

Warm Up for 7/31 A B Compare and Contrast the data represented in the boxplots above.

Warm Up for 8/ What is the 5 number summary? 2. What is the range? 3. What is the interquartile range? 4. What percent of the data is between 10 and 12?
