Discrete data involves whole numbers (integers - like 1, 356, or 9) that can't be divided based on the nature of what they are. Like the number of people in a class, the number of fingers on your hands, or the number of children someone has. You can't have 1.9 children in a family (despite what the census might say).

Why is interval data important?
Interval data is fun (and useful) because it's concerned with both the order and difference between your variables. This allows you to measure standard deviation and central tendency. Everyone's favorite example of interval data is temperatures in degrees celsius. 20 degrees C is warmer than 10, and the difference between 20 degrees ...
What is the difference between quantitative and qualitative data?
Quantitative vs Qualitative data - what's the difference? In short: quantitative means you can count it and it's numerical (think quantity - something you can count). Qualitative means you can't, and it's not numerical (think quality - categorical data instead). Boom!

Ratio data is very similar interval data, except zero means none. For ratio data, it is not possible to have negative values. For instance, height is ratio data. It is not possible to have negative height. If an object's height is zero, then there is no object. This is different than something like temperature.

What is qualitative data?
It means that this type of data can’t be counted or measured easily using numbers and therefore divided into categories. The gender of a person (male, female, or others) is a good example of this data type.

Qualitative Data Types
- Nominal data

In plain English: basically, they're labels (and nominal comes from "name" to help you remem… - Ordinal data

Thank goodness there's ratio data. It solves all our problems. Ratio data tells us about the order of variables, the differences between them, and they have that absolute zero. Which allows all sorts of calculations and inferences to be performed and drawn. Ratio data is very similar interval dat…
Introduction
- Data scienceis all about experimenting with raw or structured data. Data is the fuel that can drive a business to the right path or at least provide actionable insights that can help strategize current campaigns, easily organize the launch of new products, or try out different experiments. All these things have one common driving component and this is Data. We are entering into the digital er…
Qualitative Data Type
- Qualitative or Categorical Data describes the object under consideration using a finite set of discrete classes. It means that this type of data can’t be counted or measured easily using numbers and therefore divided into categories. The gender of a person (male, female, or others) is a good example of this data type. These are usually extracted from audio, images, or text mediu…
Quantitative Data Type
- This data type tries to quantify things and it does by considering numerical values that make it countable in nature. The price of a smartphone, discount offered, number of ratings on a product, the frequency of processor of a smartphone, or ram of that particular phone, all these things fall under the category of Quantitative data types. The key thing is that there can be an infinite numb…
Different Tests
- We have discussed all the major classifications of Data. This is important because now we can prioritize the tests to be performed on different categories. Now it makes sense to plot a histogram or frequency plot for quantitive data and a pie chart and bar plot for qualitative data. Regression analysis, where the relationship between one dependent and two or more independe…
Conclusion
- In this article, we discussed how the data we produce can turn the tables upside down, how the various categories of data are arranged according to their need. We also looked at how ordinal data types can overlap with the discrete data types. What type of plot is suitable for which category of data was also discussed along with various types of test that can be applied on spe…
