3.4 Measures of Position

Objectives:

By the end of this section, I will be

able to…

- Find percentiles for both small and large data sets.
- Calculate z-scores, and explain why we use them.
- Use z-scores to detect outliers.

18

T

Thanksgiving

Basketball

Old Joe

$35

Cali

Onion

Garth Brooks

Cricket

Comparing Scores

- Standardized Tests: SATs, TerraNovas, CTBS, ACTs
- Two ways to compare scores:
- Percentile Rank
- Z-scores

PERCENTILE RANK

# of Equal scores

Scores that came BEFORE

- B =# of scores that came BEFORE “your” score
- E =#of scores that are the same as “your” score
- N = Total #of people taking the test

Total Number

z-scores

- Numerical values that are used to compare scores
- It indicates how many standard deviations a data value is from the mean.

z-scores

MEAN

1) Find your z-score.

- Let’s find the meanfirst.
- Now find the standard deviation.

Standard Deviation

Finding an actual score

- If the average senior at UD can drink 9 beers before he/she gets sick with a standard deviation of 1.76, find the amount that the following people actually drank.

Timmy Joe who had a z-score of 5.1

Betty Sue who had a z-score of -0.957

17.976

7.316

z-scores and OUTLIERS

- If you are between -2 and 2 it is NOT unusual.
- If you are <-3 or >3 it is very unusual and it is an OUTLIER
