Reliability and validity in measurement
{"Image DocumentName": "Reliability and validity in measurement", "Image ImageDescription": "Researchers must determine measurement error, which is the difference between the information sought and the information actually obtained in the measurement process. Every measurement includes true, accurate information plus some degree of error. Measurement results. = True measurement + Measurement error. Two potential sources of error exist in the measurement process: systematic error and random error. = True measurement + (Systematic error + Random error) Validity. Reliability. \u2026 !
