Types Of Data & Graphs for Data Analysis
Once the Goal of the research is determined, the next step in the lifecycle of Data Science is Data Retrieval, which can be captured from many sources and in many forms. Once the Data is captured, we verify the types of Data or Variables, or instances we have in a dataset. There are Two Types of Data 1.) Categorical 2.) Numerical Categorical Data Type is the variables which forms a category, or groups such as Gender, or a variable that has an answer as Yes/No. they usually take fixed number of possible values. A categorical variable that can take exactly two values is also known as binary variable or dichotomous variable, and the one with more than two variables is known as polytomous variable. The Data can be further categorized as Nominal and Ordinal Data type. Nominal variable is the one that has no particular order and Ordinal Variable has a particular order. Numerical Data t...
