This course begins by teaching you how to compute for arrangements. You will study how to arrange and select objects as well as look at a group frequency table to compute for the estimated mean, median class, modal class, and range. You will also learn that a stem and leaf diagram can help you quickly summarize data while maintaining the individual data points. You will then study how to construct a stem and leaf diagram and get them in order.
Stem-and-leaf diagrams are a visual representation of grouped discrete data and are an excellent tool for organizing information. This course will teach you how to draw a comparative stem-and-leaf diagram for data. You will then look into a histogram which is a graphical display of data using bars of different heights to help you discover and visualise the underlying frequency distribution (shape) of a set of continuous data. You will also look into the probability of simple events.
Statistics looks at the data handling cycle and analysis of collected data. Upon the completion of this course, you will be able to understand the process involved in posing a question, collecting data on that question, presenting that data, analyzing the data using measures of spread and centre, and interpreting the results. So, check out the course and learn how to contextualize and justify your findings using probability and statistics to make informed decisions.
