Detailed explanation-1: -The three most commonly used methods for causal-comparative research are the chi-square test, paired-samples and independent t tests, and analysis of variance (ANOVA) or ANCOVA.
Detailed explanation-2: -Experiments are the most popular primary data collection methods in studies with causal research design. The presence of cause cause-and-effect relationships can be confirmed only if specific causal evidence exists.
Detailed explanation-3: -Two weaknesses in causal-comparative research are lack of randomization and inability to manipulate an independent variable. As we have mentioned, random assignment of subjects to groups is not possible in causal-comparative research since the groups are al-ready formed.
Detailed explanation-4: -A mixed methods research design is a procedure for collecting, analyzing, and “mixing” both quantitative and qualitative research and methods in a single study to understand a research problem.
