Answer 1

Answer:

Two main statistical methods are used in data analysis: descriptive statistics, which summarize data from a sample using indexes such as the mean or standard deviation, and inferential statistics, which draw conclusions from data that are subject to random variation (e.g., observational errors, sampling variation).

Answer 2

Answer:

The science of analyzing large amounts of data to explore the underlying patterns, trends, and hidden insights from them is called statistical analysis. Broadly speaking, there are two categories of statistical analysis. Descriptive analysis helps in summarizing the available data. It analyzes the structure and distribution of either the entire data. This analysis generates limited insights that only presents a way to summarize the data. Inferential analysis is used to deduce some insights from the data that are not apparently visible. It can be used to make judgments and infer insights from the data.
