When researching developmental trends, longitudinal studies allow you to discover changes across lifespans and arrive at valid research outcomes. Participants cannot tailor their responses or add context. This study design looks for cause and effect (if A, then B), so it requires having control over at least one of the independent, or treatment variables. Simply put, quantitative observation is an objective method of data gathering while qualitative observation is a subjective method of data gathering. In a deductive analysis, the researcher develops a research theory, builds hypotheses from this theory and tests the hypotheses by collecting and analyzing data samples using quantitative observation methods. 2010;50 Suppl 1(s1):10-2. doi: 10.1080/10408398.2010.526838.

Such statistical results may shed light on cause-and-effect relationships. Descriptive studies give us an accurate account of the characteristics of a particular situation or group. Governmental and research institutes often carry out longitudinal studies and make the data available to the public. Unlike other methods of data analysis, the quantitative analysis yields definite results that can be quantified. because the researcher observes and records changes in variables over an extended period. Changes in the dependent variables are presumed to be caused or influenced by the independent variable. Qualitative research is often focused on answering the why behind a phenomenon, correlation or behavior. In other words, a retrospective study looks backward. On the other hand, quantitative research requires a shorter time frame and results in more definite research outcomes. High: High confidence that the evidence reflects the true effect. Obtain baseline data on the exposure; measure the exposure at the start. 2022 Dec 31;18(1):1972708. doi: 10.1080/21645515.2021.1972708.
