Non-Parametric Alternative Hypothesis Tests in Business Statistics
A parametric test may be used when your data are scale level and the assumptions of the test have been met. Each of the parametric tests we have learned about has an alternative non-parametric test that can be used when your data are nominal or ordinal, your scale data are skewed or non-no

Choosing a Test, Hypothesis, and Level of Significance for Hypothesis testing (Steps 1-3) (Week 14C)
In the first step of hypothesis testing we choose the test we will use by examining the level of the data. Next, based on that test, we establish a null and alternative hypothesis. Third, we determine a criteria by which we will determine statistical significance. Lecture date: Tuesday,

Describing Distributions with Skewness, Kurtosis, Modality, & z-Scores Business Statistics (Week 6A)
The normal curve is the most important distribution in statistics. When distributions differ from normality, we describe them with kurtosis (leptokurtic, platykurtic, mesokurtic), with skewness (positive or negative), and with modality (unimodal, bimodal, multimodal). In addition to those
