Stat Mean Mode Median Variance Sd Pdf Quartile Outlier Measures of central tendency 2. median also known as q2 (from quartiles), so 50% of the values lie above and 50% of the values lie below it. For variance do steps 1 5, for standard deviation do steps 1 6. step 1 – compute the sample mean step 2 – calculate the difference of − ̅ , for each value in the data set.
Updated 2 Stat100 Median Mode Range Outlier Percentiles Problem The box plot consists of a scale, a box drawn between the first and third quartile, the median placed within the box, whiskers on both sides of the box and outliers (if any). This document provides an overview of measures of central tendency and variability used to analyze quantitative data. it discusses various measures including the mode, median, mean, percentiles, quartiles, range, interquartile range, variance and standard deviation. Standard deviation (sd) — another measure of variability to understand how standard deviation (sd) works, let’s use a small data set {1, 2, 2,7} as an example. The median md of a set of data is a number such that half of the observations are below the number and half of the observations are above that number when the data are ordered in an array from lowest to highest.

We will learn how to calculate outliers later in this section. the mean, range, variance and standard deviation are sensitive to outliers, but iqr is not (it is resistant to outliers). the median and the mode are also not affected by extreme values in the data set. 10) mode = 2 and 12, median = 6, mean = 7.6, q = 3, q = 12, iqr = 9 and = 4.63 create your own worksheets like this one with infinite algebra 1. free trial available at kutasoftware worksheet by kuta software llc. This article will cover the basic statistical functions of mean, median, mode, standard deviation of the mean, weighted averages and standard deviations, correlation coefficients, z scores, and p values. Find the mean and median with the ti 84 mean > median if data is skewed right, mean < median if data is skewed left, the mean = median if data is exactly symmetric.
