Random sample

The sample data from the athletes in the MIAA showed a correlation of -0.026, meaning there is no correlation between the two variables. The statistical tests used were both a bootstrap test and a randomization hypothesis test for a correlation. Figure 1. Scatter plot and summary statistics from the sample data. This display has the time in seconds on the X-axis and the distance in miles on the Y-axis…

Measuring validity is important because it determines the impact of research. Validity is defined as “an integrated, evaluative judgment of the degree to which empirical evidence and theoretical rationales support the adequacy and appropriateness of inferences and actions based on test scores or other modes of assessment” (Salkind, 2010, p.1). There are many criteria of rigorous research, for example, internal validity, external validity, objectivity of observer, replicability, and reliability…

an experiment. To be considered an experiment, the study must follow a strict process of scientific research. It must include an independent variable, dependent variable, random assignment and a definite hypothesis (Weiten, 2013, p. 65).…

while the second group was vaccinated with the shot. The independent variable was the vaccination and the dependent variable was how many participants came down with the flu. Following the guidelines outlined in our text, this sample is large, and "large, randomly selected samples minimize sampling error” (Tanner, 2011). Also, each group contains an equal amount of participants and was randomly…

Just because a prisoner is behind bars, that doesn’t mean they don’t have access to the outside world. With the growing rate of prisoners in the U.S. brings the growing rate of drugs into those prisons. Drug use within prisons presents several problems for the Correctional system.
