Description

## Objective:

The objective of this course is to provide a comprehensive overview of core concepts in Statistics. Emphasis is placed on the foundations of statistics; probability; correlation and regression; sampling distributions; and inferential statistics.

## Learning Outcomes:

• describe data types and levels of measurement including sample vs. population, and distribution
• understand random sampling, and the importance of randomness
• describe the distribution of a numeric variable by its center and spread
• represent numeric variable distributions graphically by dot plot, stem-and-leaf plot, box-and-whisker plot, and histogram
• discuss the center and spread of the distribution of a numeric variable
• define the normal distribution of a variable and calculate normal probabilities
• construct and analyze a scatter plot for a set of bivariate data
• calculate the regression model for a set of bivariate data and use it to make predictions
• calculate the probability of simple and compound events
• use a variety of probability distributions to calculate the probability of an event
• construct one and two sample confidence intervals for population means or proportions
• conduct one and two sample hypothesis tests for population means or proportions
• understand errors in hypothesis testing and their causes
• conduct Chi-square tests for uniformity of univariate data or independence of two categorical variables
• compare multiple population means using an ANOVA test; analyze a randomized block experiment with an F-test
