Whats the difference between correlational and experimental research? Individual Likert-type questions are generally considered ordinal data, because the items have clear rank order, but dont have an even distribution. The absolute value of a number is equal to the number without its sign. Singer, J. D., & Willett, J. You need to assess both in order to demonstrate construct validity.
In a cross-sectional study you collect data from a population at a specific point in time; in a longitudinal study you repeatedly collect data from the same sample over an extended period of time. 1. 4. How can you ensure reproducibility and replicability? Be careful to avoid leading questions, which can bias your responses. For example, you might use a ruler to measure the length of an object or a thermometer to measure its temperature. Blinding is important to reduce research bias (e.g., observer bias, demand characteristics) and ensure a studys internal validity. A confounder is a third variable that affects variables of interest and makes them seem related when they are not. This can lead you to false conclusions (Type I and II errors) about the relationship between the variables youre studying.

Using stratified sampling will allow you to obtain more precise (with lower variance) statistical estimates of whatever you are trying to measure. A cross sectional study, on the other hand, takes a snapshot of a population at a certain time, allowing conclusions about phenomena across a wide population to be drawn. Convergent validity indicates whether a test that is designed to measure a particular construct correlates with other tests that assess the same or similar construct. For example, if you are researching the opinions of students in your university, you could survey a sample of 100 students. 2 What is a cross-sectional quantitative survey?

Revised on However, peer review is also common in non-academic settings. Stefan Hunziker . A correlation reflects the strength and/or direction of the association between two or more variables. It always happens to some extentfor example, in randomized controlled trials for medical research. A case-control study is qualitative. Quantitative methods allow you to systematically measure variables and test hypotheses. Face validity and content validity are similar in that they both evaluate how suitable the content of a test is. The correlation coefficient only tells you how closely your data fit on a line, so two datasets with the same correlation coefficient can have very different slopes. However, cross-sectional studies may not provide definite . After data collection, you can use data standardization and data transformation to clean your data. These principles make sure that participation in studies is voluntary, informed, and safe. Whats the difference between extraneous and confounding variables?

If you dont control relevant extraneous variables, they may influence the outcomes of your study, and you may not be able to demonstrate that your results are really an effect of your independent variable. The information obtained from cross-sectional studies enables researchers to conduct further data analyses to explore any causal relationships in more depth. Verywell Mind. Cross-sectional studies are observational studies that analyze data from a population at a single point in time. If the people administering the treatment are aware of group assignment, they may treat participants differently and thus directly or indirectly influence the final results.
