p. 10 – Using Spread and Center. CORRECT with the EDpuzzle
3) Warm Up:
Find the mean, median, range and MAD: , 15, 25, 10

2. 50, 15, 25, 10
mean:
median:
range:
MAD:

3. Sample: A group of people or objects selected from a population.
Vocab toolkit
Sample: A group of people or objects selected from a population.
Distributions: The entire set of collected data organized to show their frequency of occurrence.

5. Team Line Plot Total $ Raised Mean (Add ∆) MAD 1 2 3 4 5 6
(Add lines) 1 2 3 4 5 6

6. Team Totals :
210
210
210
210
210
210
This method will NOT help determine the most successful team because each team raised the same amount of money.

7. Team Means : 35 35 35 35 42 35
Since the totals are the same, the means of all the teams are the same except team 5. Team 5 has only 5 members, so their mean will be higher. So, if a team’s success is measured by the average amount raised, this strategy helps determine the most successful team.

8. If a team’s success is measured in terms of variability (or low variability), this strategy helps determine the most successful team. Team 6 has the least variability – only $5 from the mean.

9. How about the median? Does it help?

10. MAD = $6

11. MAD = $6

12. HW p. 10

13. 1 MAD = 2 MAD = 1 MAD = 2 MAD = 1 MAD = 2 MAD = 1 MAD = 2 MAD =
