Answer 1

Descriptive statistics, inferential statistics, and data cleansing, imputation, and visualization are some of the statistical methodologies used by Data Analysts.

Step-by-step explanation:

Descriptive statistics is a statistical methodology used by Data Analysts to organize and summarize data. It includes methods such as graphing and finding averages. Inferential statistics is another methodology that Data Analysts utilize to draw conclusions from data using probability. It involves hypothesis testing and determining the likelihood of results occurring by chance.
