This article needs additional citations for verification. You ask participants to administer a safe electric shock to themselves and rate their pain level on a 7-point rating scale. The precision of a measurement is how close a number of An observed score may include both random and systematic errors. Random error affects your measurements in unpredictable ways: your measurements are equally likely to be higher or lower than the true values. Random error introduces variability between different measurements of the same thing, while systematic error skews your measurement away from the true value in a specific direction. In scientific research, measurement error is the difference between an observed value and the true value of something. More statistical analyses can be done with ordinal scales than with interval scales. An intoxicated perpetrator can be charged with committing sexual assault. (Select all that apply.)
