Counting things. For example, a train station that counts the number of passengers who enter the station in real time.Quantification
Converting qualitative human judgements into numbers. For example, asking customers to rate their satisfaction on a scale of 1 to 4.Calculations
Mathematical calculations such as calculating gross margin based on monthly sales figures.Estimates
