Is a cellphone number a cardinal number? Categorical data represents characteristics. The characteristics of categorical data include; lack of a standardized order scale, natural language description, takes numeric values with qualitative properties, and visualized using bar chart and pie chart. The other alternative is turning categorical data into numeric values using one of several encoding techniques. Numbers like national identification number, phone number, etc. The bar chart is used when measuring for frequency (or mode) while the pie chart is used when dealing with percentages. An uncountable finite data set has an end, while an uncountable infinite data set tends to infinity. Why would enterprises ignore an entire class of data?
