| Term | Definition |
|---|---|
| Confidence Interval | the range of values within which you are confident the actual mean lies |
| Standard Deviation | describes the variability in the data |
| Alpha | the significance level, the probability that the real mean lies outside the confidence interval |
| T-Test | a test that strengthens a conclusion that the means of two groups are really different from each other (probability that there is no real difference between the groups) |
| Lower or Higher T-Test is better? | a lower t-test is better |
| One-Tail Test | appropriate if our hypothesis states that one group is larger or smaller than the other |
| Two-Tail Test | if it is predicted that the means of the two groups would be different |
| Type 1 | for paired samples, like before and after testing. Ex. comparing people before and after taking vitamin C |
| Type 2 | for non-paired samples, though the variance is known |
| Type 3 | for non-paired samples, though the variance is unknown |
| Law of Large Number | a large number of items chosen at random from a population are bound, on average, to have the characteristics of the population |
