Statistics is the science of collecting, organizing, analyzing, interpreting, and presenting data. Data science is a newer field that combines statistics with computer science and other disciplines to extract insights from data.
2. What are the different types of statistics?
There are many different types of statistics, including descriptive statistics, inferential statistics, and Bayesian statistics. Descriptive statistics describe the data set in a specific way, such as as by finding the mean or the median, while inferential statistics use the data to make predictions about the population from which the data was drawn. Bayesian statistics is a newer approach to statistics that uses probability to update beliefs as new data is collected.
3. What are the most common statistical methods?
Some of the most common statistical methods include:
- Hypothesis testing
- Regression analysis
- Analysis of variance
- Factor analysis
- Cluster analysis
