Module 1 Descriptive Statistics Pdf Mean Statistics Additionally, it covers methods for presenting data graphically and the concept of descriptive statistics, including measures of location such as mean, median, and mode. 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.
Descriptive Statistics Part 1 Pdf Mean Median Find the mean, median, mode and standard deviation of: a) day 1 to 3 b) day 1, 2 and 3 individually problem 1 b a production supervisor of xyz company is evaluating three alternative procedures for processing a job order. Procedures used to summarize, organize, and simplify data (data being a collection of measurements or observations) taken from a sample (i.e., mean, median, mode). Standard deviation is a statistical measure of the amount of variation or dispersion in a set of data points. it provides a way to quantify how spread out the values in a dataset are from the mean (average). in other words, it measures the average distance between each data point and the mean. Descriptive statistics is the discipline of qualitatively describing the main fea tures of some data. it di ers from inferential statistics in that the former aim to summarize a sample, whereas the latter uses the data to learn about the popula tion that the sample is meant to represent.

(a) descriptive statistics it deals with the presentation of numerical facts, or data, in either tables or graphs form, and with the methodology of analysing the data. Descriptive statistics includes statistical procedures used to describe the population or group being studied. the results cannot be generalized to any larger group. the data could be collected from either a sample or a population, but the results help one to organize and describe data. The document discusses descriptive statistics, which are used to describe and analyze data through measures of central tendency (mean, median, mode) and measures of variability (range, variance, standard deviation). Introduction to descriptive and inferential statistics. the role of statistics . the goal of virtually all quantitative research studies is to identify and describe relationships among constructs. data are collected in a very systematic manner and conclusions are drawn based on the data.
