Chapter 3 Describing Data Numerical Measures Pdf Mean Quartile The mean, median, mode, percentiles, range, variance, and standard deviation are the most commonly used numerical measures for quantitative data. the mean, often called the average, is computed by adding all the data values for a variable and dividing the sum by the number of data values. In this chapter, you learn to: describe the properties of central tendency, variation, and shape in numerical data construct and interpret a boxplot compute descriptive summary measures for a population calculate the covariance and the coefficient of correlation.
Chapter 3 Describing Data Using Numerical Measures Pdf In this lesson you will learn how to describe data with numbers. the two most important summaries of data for a quantitative variable are those for the center and the spread. Describe which measure of central tendency— mean, median or mode was probably used in each situation. one half of the factory workers make more than $5.37 per hour, and one half make less than $5.37 per hour. median. Explain the characteristics, uses, advantages, and disadvantages of each measure of location. identify the position of the mean, median, and mode for both symmetric and skewed distributions. compute and interpret the range, the mean deviation, variance, and the standard deviation. This lesson considers important numerical summaries for measures of center and spread, including the mean, median, mode, range, variance, and standard deviation, to describe univariate, quantitative (numeric) data.
Chapter 02 Describing Data With Numerical Measures Pdf Mode Explain the characteristics, uses, advantages, and disadvantages of each measure of location. identify the position of the mean, median, and mode for both symmetric and skewed distributions. compute and interpret the range, the mean deviation, variance, and the standard deviation. This lesson considers important numerical summaries for measures of center and spread, including the mean, median, mode, range, variance, and standard deviation, to describe univariate, quantitative (numeric) data. This document provides examples and exercises for calculating and interpreting various numerical measures that describe data, including the mean, median, standard deviation, variance, range, and interquartile range. Definition: descriptive statistics (also called summary statistics) uses graphical and or numerical summaries for describing or summarizing data from a sample. the most common descriptive statistics provide information about a sample’s central tendency (mean, median, mode) and variability (variance, standard deviation, range). Identify and compute the arithmetic mean. compute and interpret the weighted mean. determine the median. identify the mode. explain and apply measures of dispersion. compute and explain the variance and the standard deviation. explain chebyshev’s theorem and the empirical rule. Chapter 3: numerical descriptions of data chapter 1 discussed what a population, sample, parameter, and statistic are, and how to take different types of samples. chapter 2 discussed ways to graphically display data.
