- Uncover causality between one dependent variable and one or more independent variables here.Suppose that in a research it was discovered that those who majored in math, engineering, or computer science scored higher on tests measuring "problem-solving" ability at the end of 4 years of college than did those students who did not major in these fields. What is the dependent variable in this study? Is the dependent variable clearly defined?Why would the male lifespan not be the dependent variable?
- 2. What are independent and dependent variables from this table ?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:An experiment is conducted to examine the effects of ingesting hot dogs, pizza, ice cream, sour milk, and carrot juice in one setting and the time it takes to get the first sign of an upset stomach. What are the independent and dependent variables (explain)?
