What is a confounding variable? What is an example of a qualitative variable? Fill in the blank: in regression problems, the explanatory variable is referred to as the independent variable and the response vari

What is the difference between correlation research and experimental method? What is a confounding variable? What is the difference between the setting, the population and the sample of a research study? How can one write a correlational research report?
Example: Control variable It is very possible that if a student feels ill, they will get a lower score on the exam. However, we are not interested in measuring health outcomes a part of our research. This makes “health” a good candidate for a control variable. It still impacts our res...
In this type of study design, researchers will quantify two variables of relevance to their research question, and then statistically determine if the two variables are related to one another. For a correlational study, we may ask research questions such as: Is there a relationship between the ...
Two-way ANOVA, also known as two-way (or two-factor) analysis of variance, extends the One-Way ANOVA by incorporating two independent variables. It is used to estimate how the mean of a quantitative variable changes when influenced by two factors. ...
A third precondition for causation is the lack of a confounding variable (also known as a confounder). You may observe that drinking coffee is correlated with heart disease later in life. Here you have our first two preconditions satisfied: correlation and temporal precedence. However, there may...
What is an example of a qualitative variable? What is the difference between correlation research and experimental method? Explain the continuous or scale variables in research with examples. What is a confounding variable? What are independent variables and dependent variables? What is the diffe...
