Logic of Hypothesis Testing (08:19)


A hypothesis is a prediction about a population. If the probability of the sample results occur by chance is low, then the hypothesis is supported; however, if the chances are high, the hypothesis is not supported.

Process of Hypothesis Testing (20:38)

The steps of hypothesis testing are to define the null and research hypothesis, determine the characteristics of the comparison distribution, establish a Z-cutoff score, calculate Z-scores, plot calculated Z-scores on the comparison distributions, and draw conclusions about the hypothesis.

One and Two-Tailed Tests (05:59)

Lowe defines and distinguishes between one and two-tailed tests. Examples of two- tailed and one- tailed tests are demonstrated.

Significance in Research Articles (07:48)

Significance, in statistics, means the null hypothesis was rejected and the alternative hypothesis was supported. Significance is not due to chance.
