UPDATE
1. Peer review - ANSWER- is a process in which several experts in a
field evaluate a research report BEFORE the report is published.
2. Selection bias (selection effect) - ANSWER- Occurs when researchers
select their sample in a bias way.
3. Participation bias - ANSWER- Occurs anytime participation in a study
is voluntary.
4. Self-selected survey (voluntary response survey) - ANSWER- people
decide for themselves whether to participate.
5. Statistics (The Science) - ANSWER- collecting, organizing, and
interpreting data
Page 1 of 18
, 6. Statistics (The Thing) - ANSWER- The data that describes or
summarizes something.
7. Population - ANSWER- Complete set of people or things being
studied.
(This set is usually too large to reasonably directly calculate anything.)
8. Population Parameter - ANSWER- specific numbers describing the
specific characteristics of the population. (You can almost never have
this exact number so we just get close enough... using statistics!)
9. Sample - ANSWER- Subset of the population from which data are
actually obtained.
10.Sample Statistic - ANSWER- numbers describing characteristics of
the sample found by consolidating or summarizing the raw data
11.Raw Data - ANSWER- actual measurements/observations collected
from sample
12.margin of error - ANSWER- used to calculate range of values.
(Confidence Interval defined as 95%)
Page 2 of 18
, 13.confidence interval - ANSWER- the range of values within which a
population parameter is estimated to lie.
14.Suppose we have a sample statistic of average height of 5.25 feet at a
high school. Also, the margin of error is plus or minus .25 feet. What
is the confidence interval? - ANSWER- Confidence interval is from 5
feet to 5.5 feet. The hope is that with 95% accuracy the actual average
height of everyone at the high school is between 5 feet and 5.5 feet.
15.Steps in a statistical study - ANSWER- 1. Goals
2. Population
3. Study subject
4. Choose representative sample
5. Collect raw data
6. Summarize
7. Make inference about population
8. Draw conclusions (what was learned? were our
goals reached?
