WGU C955 Probability and Statistics Solved 100%

WGU C955 Probability and Statistics Solved 100% Boxplot - ANSan image that has min, Q1, median, Q3, max Histogram - ANSA graphical representation -- bars, measuring the frequency within each interval Skewed right - ANSNot a symmetric distribution, the tail is on the right, i.e. extra stuff on the right Measures of center - ANSMedian, the mean (and mode) Measures of spread - ANSRange, IQR & standard deviation Standard Deviation Rule - ANS68% of the data are within 1 standard deviation, 95% are within 2, 99.7 are within 3 standard deviations from the mean. For skewed data, use these for center and spread - ANSIn this situation, we use median (for center) & IQR (for spread) Explanatory variable - ANSIn a study, what we think is the "cause" Response variable - ANSIn a study, what we think is the "effect" Scatter plot - ANSA graphical representation of Q -> Q Two way table - ANSA graphical representation of C -> C Side-by side box - ANSA graphical representation of C -> Q Linear relationship - ANS"shaped like a line" Correlation coefficient, r - ANSBetween
