Document Summary
Starting to make decisions about how you answer the question. Decisions made at this point in the process determine the conclusions that you can draw from your results. Step 2: if quantitative, determine the stage of knowledge. Looking for trends among individual participants or people. Have to consider a lot of variables, because you don"t know what might be affected and what variables to consider. Evaluating whether one explanation (theory) applies to multiple participants. Ex: children are eating very poorly because both parents work, therefore there is no one allocated to monitoring the nutrition of the family. What is the relationship you are interested in establishing between variables: correlational designs. Determine whether 2 or more variables covary. Establish the directions, magnitudes or form of relationship. Determine how changes in one variable directly or indirectly determine changes in another variable. Step 4: determine the types of methods to use. Behavior is observed as it naturally occurs.
