Slide1Statistics and Data(Algebraic)

Slide3Parameters and StatisticsMean, Median, and Mode The Five-Number Summary Boxplots Variance and Standard Deviation Normal Distributions … and why The language of statistics is becoming more commonplace in our everyday world.

Slide5The median  of a list of n numbers { x 1 , x 2 ,…, x n } arranged in order (either ascending or descending) is the middle number if  n  is odd, and the mean of the two middle numbers if  n  is even.

Slide6The mode  of a list of numbers is the number that appears most frequently in the list.

Slide7find the (a) mean, (b) median, and (c) mode of the data:                                                                               3, 6, 5, 7, 8, 10, 6, 2, 4, 6

Slide11A number in a data set can be considered anoutlier  if it is more than 1.5 × IQR  below the first quartile or above the third quartile.

Slide14if the data for a population are normally distributed withmean  μ  and standard deviation  σ , then Approximately 68% of the data lie between  μ  - 1 σ  and μ  + 1 σ . Approximately 95% of the data lie between  μ  - 2 σ  and μ  + 2 σ . Approximately 99.7% of the data lie between  μ  - 3 σ and  μ  + 3 σ .
