- Hypothesis testing (e.g., t-tests, chi-square tests)
- Regression analysis (e.g., linear regression, multiple regression)
Hypothesis Testing and Statistical Inference
The textbook explains the concepts of hypothesis testing and statistical inference, enabling students to make informed decisions based on data. It covers topics such as null and alternative hypotheses, p-values, and confidence intervals.
Examples and Applications, Statistics for business and economics 14th edition pdf
- Testing the effectiveness of a new product launch
- Determining if there is a significant difference in customer satisfaction between two competing brands
- Estimating the population mean with a given level of confidence
Regression Analysis
The textbook provides a comprehensive treatment of regression analysis, covering both linear and multiple regression models. It emphasizes the use of regression models to predict outcomes and identify relationships between variables.
Principles and Applications
- Principles of linear regression (e.g., least squares estimation, model assumptions)
- Multiple regression models (e.g., variable selection, model interpretation)
- Applications in business (e.g., forecasting sales, optimizing marketing campaigns)
Time Series Analysis
The textbook introduces time series analysis, covering techniques for analyzing and forecasting time-dependent data. It covers topics such as stationarity, autocorrelation, and forecasting methods.
Concepts and Techniques

- Forecasting methods (e.g., moving averages, exponential smoothing)
- Applications in business (e.g., forecasting economic indicators, demand forecasting)
Non-Parametric Tests
The textbook introduces non-parametric tests, which are used when the assumptions of parametric tests are not met. It covers topics such as the chi-square test, the Kruskal-Wallis test, and the Mann-Whitney U test.
Types and Applications
- Chi-square test (e.g., testing independence between variables)
- Kruskal-Wallis test (e.g., comparing medians of multiple groups)
- Mann-Whitney U test (e.g., comparing medians of two groups)
