This is a C++ Code for Mean Grouped. Dataset is user input. Code Explanation: size will hold how many datasets to be inserted, data will hold the inputted data, freq will hold the frequency of each data, XiFi will hold the results for each data multiplied by each frequency. Then the data will compute the mean of the dataset. It will display the ff: Summation of total observations (variable : sXiFi) Summation of total frequencies (variable : sfreq) Mean Value (variable : mean)
Typology: Lab Reports
