Within your area of interest (autism), develop a research question that can make use Correlation or Regression analysis. In correlational studies, we typically call the independent variable the predictor and the dependent variable the criterion.
Be sure to include the following steps:
State your Research Question
Identify the variables in the study and explain how they will be measured. For each variable, identify the scale of measurement (nominal, ordinal, interval, or ratio), and identify whether the variable is an independent variable (controlled or manipulated ID! the researcher) or a dependent variable (the outcome of interest). If you have trouble understanding the difference between independent variables and dependent variables, a tip from Howell (2012) may be helpful. In every study, you will collect da to analyze. The words data and dependent both begin with d. Thus, the data you collect to analyze constitute the dependent variable.
Independent Variable: Dependent Variable or Criterion: State the hypothesis (null and altemate).
E careful with your wording: Is your altemate hypothesis directional or non-directional
State why a Correlation or Regression analysis would be the best type of test to answer your research question.
