Quantitative data can be analyzed in a variety of different ways. Hypothesis Testing and the Statistics T-Test. There are two main approaches to choose from here: Grounded theory / emergent coding / inductive (data driven) This is where you don’t know beforehand what you are looking for in the data, and identify topics as you are reading it: you are creating theory on the fly.

Data Analysis is simpler and faster with Excel analytics. On the other hand, various types of qualitative data can be represented in nominal form. What Is Data Analysis? The initial data set I went to find was a statistically backed source of media bias and truthfulness. Survey data analysis—aggregating the numbers.

Ratio data is said to be the richest form of survey data. C. generalized data B. consolidated data D. data analysis 6.
