Which term describes the most frequently occurring value in a data set? 1. mode 2. mean 3. range 4. median Correct Answer 1. mode Why is it important to determine if a sample is normally distributed? 1. Because larger samples are usually not normally distributed 2. Because we cannot run statistical tests on samples that are not normally distributed 3. Because a normally distributed sample does not require advanced statistical tests 4. Because it will determine whether you can use a pa...

Statistics vs. Parameters - analysis on a sample vs. Analysis on the entire population Overview to data analysis - quantitative: descriptive and inferential Descriptive: simply describe a characteristic of a population/sample or a phenomenon Inferential: hope to generalize from a sample to a population (based on probability)--we use parametric and non-parametric statistics Parametric tests and non-parametric tests - every statistical test has assumptions that must be met Parametric t...

When we have Pearson's correlation we know that we have two continuous variables They have met the assumption of normality (bc this is a parametric test) We're looking at correlation to see if there is a relationship between these two variables If you do not meet normality, or have variables that are measured on an ordinal scale (likert scale, pain scale, military rank, etc), then a non parametric equivalent would need to be ran Correct Answer What is Pearson's correlation? If you do n...
