tion P(z<a) denote
2. point estimate A point estimate is a single value used to approximate a population para-
meter
3. Z-score When a data value is converted to a standardized scale representing the
number of standard deviations the data value lies from the mean, we call
the new value a ____________________.
4. s The symbol for sample standard deviation is __________________.
5. Degrees of Freedom Degrees of Freedom Number of data points that are free to vary based on
the person who is responding (ex: mood that day, etc.; gender is the same
every day)
6. Population Population The entire collection of individuals for about which information
is sought.
7. Sample A subset of a population containing individuals who are actually observed.
8. Simple Random Sam- Every sample of size n has the same chance of be being chosen (selected).
