Chapter 2 Descriptive Statistics Pdf Mean Median It discusses key concepts like measures of central tendency (mean, median, mode), measures of variability (range, standard deviation), and ways to display data through frequency tables and charts. the mean, median, and mode are explained as the most common measures of central tendency used to summarize data. Compute the mean, median, mode, and midrange. calculate the mean, mode and median of the following data. mean=mode=median=1. the table shows the speed of the tracks passing through a hilling road. 16. 44. find the mean, mode and median. hence, identify the shape of distribution based on measures on central tendency. (minimum) xmax highest va.
Chapter 5 Descriptive Statistic Part 2 New Pdf Mode Statistics There are three common ways of describing the centre of a set of numbers. they are the mean, the median and the mode and are calculated as follows. the mean add up all the numbers and divide by how many numbers there are. the median is the middle number. it is found by putting the numbers in order.

Measuring center: the median because the mean cannot resist the influence of extreme observations, it is not a resistant measure of center. another common measure of center is the median. the median, m, is the midpoint of a distribution, the number such that half of the observations are smaller and the other half are larger. The most commonly used measures of location are: mean, median, and mode. limitation: oversensitive to extreme values; in which case, it may not be representative of the location of the majority of sample points. It also describes numerical methods for describing data, such as measures of central tendency (mean, median, mode), measures of dispersion (range, standard deviation, variance), and measures of central position (quartiles). examples are provided to illustrate how to construct and interpret these different graphs and analyses. numerical methods.
