Scenario 1: A researcher suspects that the response variable is linearly related to two explanatory variables but believes that the explanatory variables are not correlated.

- Which model would be most appropriate? (Enter 1 for first order with no interaction or 2 for second order with no interaction)

Scenario 2: Suppose the researcher thinks that the response variable may be nonlinearly related to one or both explanatory variables that may interact with each other. The researcher also wants to keep the model as simple as practical.

- Which model would be most appropriate? (Enter a whole number for order followed by either W for interaction or N for no interaction, as in 1W, no spaces)

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

There is an interaction effect between two independent variables when the effect of an independent variable differs depending on the level of another independent variable. True False
You hypothesize that there may be a non-linear relationship between your predictors, where there may be more mosquitoes in sites with water and with caribou hosts. How do you create your model? Assume that "caribou" corresponds to the presence/absence of caribou Assume that "water" corresponds to the presence/absence of water number of mosquitoes ~ caribou * water number of mosquitoes ~ caribou + water presence/absence of mosquitoes ~ caribou + water presence/absence of mosquitoes ~ caribou * water
A researcher wants to see if gender and / or income affects the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affects the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables affected total help if he rejects the null hypothesis. Below is the data set followed by the results:

What is the Independent variable and the dependent variable of this problem? A neuropsychologist is studying brainlateralization—the degree to which thecontrol of various cognitive functions islocalized more in one cerebral hemispherethan the other. This researcher is awarethat for men, being right-handed seemsto be associated with a greater degree oflateralization than does being left-handedbut that this relationship may not applyto women, who seem to be less lateralizedin general. Various tasks are used in combination to derive a lateralization scorefor each subject as shown in the followingtable.

Why do we include a disturbance term in a regression model? (1). Some determinants of the independent variable may be omitted or left out. (II). There may be measurement errors of the dependent variables that cannot be modelled. (III). There may be random influences on the independent variable which cannot be modelled, e.g. a hurricane, a computer failure. Choose from (a), (b), (c) and (d).
