Quantitative data is information that is measured and verified by numbers. For example, if a student wanted to find out the number of Metro North commuters who has an iPhone vs. an Android, he/she may hand out a survey to gather this information, then tabulate the results. The results can be shown by a pie or line chart. Other ways to depict the results could be a bar graph and/or a table.
Qualitative data is information that approximates and characterizes.. There are no numbers involved, and it is abstract. This type of data is collected through observations, interviews and focus groups. Qualitative data in statistics is also known as categorical data because this data can be grouped according to categories. Using the above example, if the student wish to know how Metro North commuters feel about their mobile devices, then he/she may conduct a very brief interview during rush hour.
In a nutshell, the main difference between qualitative and quantitative data is that qualitative data doesn't involve numbers whereas quantitative data is all about measurable information that show results in numbers.
