What you'll learn

Course skills and outcomes

Introduction to Statistics

• Evaluate the use of statistics in real-world applications.
• Describe descriptive and inferential statistical methods and the fundamental elements of statistics.
• Differentiate between qualitative and quantitative variables.
• Create visual representations of quantitative and qualitative data.
• Describe the distribution of quantitative data in terms of shape, center, and spread.

Probability Concepts, Central Tendency, and Variability

• Calculate central tendency and variability in the context of data sets, accounting for possible effects of extreme data points.
• Differentiate between discrete, continuous, and conditional probability.
• Describe how independence and conditional probability are applied in interpreting data.
• Calculate probabilities of compound events in a uniform probability model by applying the rules of probability.
• Evaluate the need to calculate expected values for the purpose of solving problems.
• Describe how the characteristics of standard normal distribution and the Empirical Rule can be used to interpret the significance of standard deviation.

Introduction to Inferential Statistics and Test of Hypothesis

• Evaluate the steps of hypothesis testing.
• Determine the distribution of the sample mean and the distribution of the sample.
• Distinguish an hypothesis regarding a population proportion verses a hypothesis regarding a population mean.
• Distinguish between the t-test and z-test.
• Determine statistically whether to accept or reject the null hypothesis.
• Interpret the results of a hypothesis test.

Chi-square Applications

• State the steps of the decision rule for a hypothesis regarding the standard deviation.
• Perform a chi-square test using equal and unequal expected frequencies.
• Determine normality using a goodness-of-fit test.
• Interpret relative frequencies in the context of the data.
• Investigate patterns of association in bivariate data using scatter plots.

Regression and Correlation

• Use technology to calculate coefficient of correlation and coefficient of determination.
• Distinguish between correlation and causation.
• Develop a single linear regression equation.
• Predict the value of y for a given value of x using a single linear regression equation.
• Apply analysis of residuals, standard error of estimate, confidence intervals, and prediction.

Review of Topics and Objectives

• Review course topics and objectives.
• Apply statistics to real-world scenarios.
