According to Sheperis, Young, and Daniels (2017), choosing appropriate instruments ensures that the data collected are both accurate and meaningful. Three common examples of research instruments include surveys, interviews, and observational checklists. Surveys and questionnaires are commonly used to gather information about participants' attitudes, beliefs, or behaviors. These instruments often include structured questions, such as Likert-scale items, that allow researchers to quantify responses and analyze trends across groups (Sheperis et al., 2017). Interviews, on the other hand, are typically used in qualitative research to gain deeper insight into participants' experiences. They can be structured, semi-structured, or unstructured, depending on how much flexibility the researcher needs. Interviews provide rich, detailed data but require careful attention to how questions are asked. Lastly, observational checklists are used to systematically record behaviors or events as they occur. This type of instrument is especially useful in clinical or natural settings where direct observation is needed (Sheperis et al., 2017). A key issue that affects the use of research instruments is researcher bias. Researcher bias refers to the ways a researcher's personal be. Need Assignment Help?
