median vs IQR - Answer skewed data uses these for center and spread Histogram - when to use - Answer Based on the shape of the distribution, uses mean + standard deviation OR median + IQR to describe center and spread - Larger data sets; shows shapes of distribution and potential outliers; ignores the individual data valuesl Histogram Skewed right - Answer Not a symmetric distribution, the tail is on the right Standard Deviation Rule - Answer 68% of the data are within 1 standard...

Boxplot - Answer an image that has min, Q1, median, Q3, max Histogram - Answer A graphical representation -- bars, measuring the frequency within each interval Skewed right - Answer Not a symmetric distribution, the tail is on the right, i.e. extra stuff on the right Measures of center - Answer Median, the mean (and mode) Measures of spread - Answer Range, IQR & standard deviation Standard Deviation Rule - Answer 68% of the data are within 1 standard deviation, 95% are within 2, 9...

skewed right - Answer A skewed distribution where the long tail of the curve is on the positive side of the peak. skewness - Answer A measure of the degree to which a probability distribution "leans" toward one side of the average, where the median and mean are not the same. the Standard Deviation Rule - Answer A standard proportion or percentage of data points that lie within each standard deviation away from the mean for a normal distribution. symmetry - Answer The quality of the da...

empirical probability - Answer An estimation of probability derived from recording data about what has happened during a series of experiments. complement - Answer An event that is the opposite of another event. The complement of heads when flipping coins is tails. The probabilities of an event and its complement always sum to 1. independent events - Answer Events, where the occurrence of one does not affect the probability that the other event(s) will occur. event - Answer An outcome, ...

Order of Operations - Answer A set of rules that defines the order in which mathematical operations should be performed. unlike terms - Answer Terms that do not have the same variable(s) with the same exponent(s). These terms can not be combined using addition or subtraction. ordered pairs - Answer Two numbers written in the form (x, y), where x represent the x-value or x-coordinate, and y represents the y-value or y-coordinate. equation - Answer Two mathematical expressions separated b...
