What is/are constant(s) within an experiment?
Select one:
a. Response (dependent) variables which must be kept the same throughout the experiment.
b. Any variable, other than the explanatory (independent) variable, which is/are kept the same between treatments.
c. Variables, other than the response (dependent variable), which are varied throughout the experiment.
d. Explanatory (independent) variables which require controls.
Homework Answers
Option A and B are correct
Because throughout the experiment they are kept same.
Dependent variables are kept same.

In regression, we call Y the response or dependent variable, which is modeled in terms of one or more "independent" variables. The independent variables are further classified as explanatory/causal variables or as predictor variables. Discuss and elaborate on whether or not time can be a legitimate explanatory/causal variable, whether time can be a legitimate predictor variable whether a predictor variable must also be a causal/explanatory variable. Provide examples to support your arguments.

Part I. Understanding What Makes an Experiment 1) Please identify the 3 vital components of an experiment. After identifying each component, write at least one sentence elaborating on/explaining each component (10 points) Answer – The most conventional type of experiment involves three major pairs of components: independent and dependent variables, pretesting and post testing, and experimental and control groups. An experiment examines the effects of independent variable on a dependent variable. 1- Manipulate at least one independent variable. This means...

Select all of the following statements that are true about linear regression analysis of quantitative variables. If the purpose of our regression model is prediction, it does not matter which variables we define as the explanatory and response variable. The observed values of Y will fall on the estimated regression line, while the predicted values of Y will vary around the regression line. The purpose of linear regression is to investigate if there exists a linear relationship between a response...

Answer the following: Please write this in computer Select two variables, one independent variable and the other the dependent variable. Explain the cause and effect the relation between the two. How would you construct the Simple Linear Regression (quantity of data and how you will measure the results), and what would you use to validate the equation forecasting an x value. What will be your expectation of the results of this investigation?
