| | | |
3. tables, graphs, or numerical summary tool
| | | | | |
4. identification of patterns in data

| | | | |
4. inference about the population based on information contained in the sample
| | | | | | | | | | | |
5. a measure of reliability for the inference
| | | | | | |
population - CORRECT ANSWER✔✔-a set of units we are studying
| | | | | | | | |
, variable - CORRECT ANSWER✔✔-characteristic or property of an individual
| | | | | | | | |
experimental unit |
sample - CORRECT ANSWER✔✔-a subset of the units of a population
