SAMPLE Introduction to Psychology
Example: The taller plant growth is due to a higher concentration of nutrientsinthesoilofthespecific area. 4. Experiment : In this step, scientists designandcarryoutexperimentstotesttheirhypothesis. They carefully plan the procedures, variables, and controls to ensure reliable and valid results. Example:Conductcontrolledexperimentswithtwogroupsofplants,onegroupinthesoilfromthespecific areaandanothergroupinthesoilfromadifferentarea,keepingotherconditionscontrolledexceptforthe soil composition. 5.

Example: Communicate the findings through scientific papers, presentations, or othermeans,including the methodology, data, and conclusions, for other researchers to review and potentially build upon. B. Research Design & Methods Research Design In the research process, the research design typically comes before determining the research methods . The research design outlines the overall structure and plan of the study, while the research methodsrefertothespecifictechniquesandproceduresusedtocollectandanalyzedata. Ithelpsguide researchers in making choices about the appropriate research methods to employ. This includes selecting data collection methods (e.g., surveys, interviews, experiments), sampling techniques, data analysistechniques(e.g.,statisticalanalysis,contentanalysis),andanyothernecessaryproceduresfor data collection and analysis. Three distinct research designs, known as cross-sectional study, cross-sequential study, and longitudinal study, will be discussed below. 1. LongitudinalStudy: Involvesstudyingthesamegroupofindividualsoveranextendedperiodof time to observe changes and developments. 2. Cross-Sectional Study: Compares individuals from different age groups at a specific point in time to examine differences and relationships.
