Which of the following is a true statement? Regression analysis and ANOVA are similar tools because they both determine if an independent variable has an effect on a quantitative dependent variable, but in ANOVA the independent variable is qualitative and in Regression analysis the independent variable in quantitative. Regression analysis and ANOVA are similar tools because they both determine if a qualitative independent variable has an effect on a quantitative dependent variable. Regression analysis and ANOVA are similar tools because...
2. For the following testable hypotheses, identify the independent and dependent variable. Hypothesis: A person's resting heart rate will drop after cycling for 1 hour 3x per week for three months. INDEPENDENT VARIABLE DEPENDENT VARIABLE Hypothesis: In a patient with a bacterial blood infection, 50 mg of penicillin applied once in an IV drip will kill more bacteria than giving the patient 50 mg of penicillin in a single pill ingested orally. NDEPENDENT VARIABLE DEPENDENT VARIABLE Hypothesis: The frequency of...
In a regression analysis, the variable that is used to predict the dependent variable a. is the independent variable b. must have the same units as the variable doing the predicting c. is the dependent variable d. usually is denoted by x
In controlled comparison research, the observed relationship between an independent variable (X) and a dependent variable (Y) may be caused by some other, uncontrolled compositional difference (Z). So, we always ask, “How else, besides the independent variable, are the groups I am comparing not the same?” For the hypothesis below, do the following: (i) Think up a plausible alternative causal variable. (ii) Describe how this variable might affect the relationship between the independent variable and the dependent variable. In a...
(3 points) Identify the independent variable, dependent variable, and causal statement in this example: "A dry cleaning company institutes a “frequent cleaner” plan where $1 is taken off the price of a dry cleaning order for every ten times a customer uses the dry cleaning company. Sales at the end of three months increase by $10,000."
Identify the independent and dependent variables in the study below. Also include the different levels of each independent variable 1. A developmental psychologist is studying memory development in children. He is interested in determining the exact age at which children begin to recall long term, episodic memories. He compares the frequency and accuracy of long term memories between groups of children aged 2.5, 3, 3.5, 4, 4.5, and 5 yrs old INDEPENDENT VARIABLE? levels of the INDEPENDENT VARIABLE? DEPENDENT VARIABLE?
