| Orthogonal comparison- means in different directions do this test |
|
|
Term
|
Definition
| accounts for type 1 error |

Term
|
Definition
| using the G for only 2 groups in post hoc helps control for this |
|
|
Term
| analyses of variance in which more than one factor is employed, test for sig diff b/t groups for each factor and interactions, and instead of only 1 SS, we now have 3 |

Term
|
Definition
| the effect of solely the IV ( A or B) |
|
|
Term
|
Definition
used with 2 or more variables that exist in the real world so there is no experimental manipulation, no IV, no DV.
desribes and measures the direction and degree of relationship b/t 2 or more variables. gather data on individuals instead of testing differences b/t means of diff groups |

|
Term
|
Definition
| measure of central tendency for data that is plotted, predict values of other variables, high correlation lets it predict, |

Term
|
Definition
| measures direction of relationship, form of relationship, and strength/consitency of relationship |
|

|
|
Term
|
Definition
| used for prediction, validity, reliability, theory verification |
|
|
Term
|
Definition
non parametric tests since they make few if any assumptions about the population distribution
less sensitive than parametric tests since there is a better chance of type 2 error
uses nominal and ordinal data |

|
Definition
| data values that are known |
|
|
Term
| chi square for independence |
|
Definition
| same test as goodness of fit but different purpose, see if there is a difference between 2 groups on a particular variable. |
