In longitudinal studies, the researcher doesnt interfere with the participants day-to-day activities in any way. In a panel study, the researcher uses data collection methods like surveys to gather information from a fixed number of variables at regular but distant intervals, often spinning into a few years. However, these outcomes have a margin of error which is the level of error in results arrived at from analyzing random sampling surveys. There exists a fundamental distinction between two types of data . Researchers must consider their hypotheses and what forms of data collection and analysis are likely to produce the most relevant findings. 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.
