MATH 106 Chapter Notes - Chapter 1-6: Summation, Frequency Distribution, Sample Space
Document Summary
Graph we chose depends on the data type that we summarized. Excel functions: =sum (, =count (, =counta (, =countif (, =min (, =max (, array function=frequency () Cntrl+shift+enter: relative reference, absolute references, mixed references. Average=add the x values and divide by n. Range: difference between smallest value and largest value. You compute the range of the middle of the middle 50% of the data. There will not be any outliers in an iqr. An observation in the data set is an outlier if it falls either below the lower fence or above the upper fence. If x is greater than 27885 is a logical test. *if x is below ,887. 5, then x is an outlier. Sample variance is decided by an unbiased estimator for the population variance. 100% is the total percentage of the data in a distribution. The mean and the median are in the same location.
