2. 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?

3. Warm Up Do not talk to your partners! Calculate the measures of central tendency and spread for this data: 1 2 6 3 2 4 3 5

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

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

6. 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

7. Five Number Summary Split this data in half. 34 40 52 57 60 60 63 67 69 69 71 89 Now, split it into fourths. These values become the FIVE NUMBER SUMMARY of the data.
