Project Description: The present study shows data for sales of different sports equipment in 2017 in a sports supplies store. The sales are provided per month. We will identify the type of data for different variables and their measurement levels. We will analyze the data numerically using measures of central tendency (mean, median, minimum and maximum) and variability (range, interquartile range, standard deviation and variance). We will construct a frequency table and investigate the relationship between variables by analyzing the correlation. We will also represent the data graphically by using line charts and pie charts. Instructions: For the purpose of grading the project you are required to perform the verey short 27 steps
