null hypothesis (H0) - the statistical hypothesis tested by the statistical procedure; usually a hypothesis of no difference or no relationship Interquartile Range (IQR) - the difference between the first and third quartiles (middle 50% of observations) dichotomous measure - describes the presence or absence of an attribute (ex smoker/nonsmoker) nominal data - categories that vary with no natural order (ex blood types) ordinal data - categories with natural order but without clear units (e...

Frequencies  Just the count or number of observations in each category. Abbreviated as 'n' or 'f' Relative Frequency  The number of times a particular observation occurs divided by the total number of observations. Frequency Distribution  A summary of the numerical counts of the values or categories of a measurement. Cumulative Frequency  The number of observations with a value less than the maximum value of the variable interval. Cumulative Relative Frequency...
