Introduction to the Practice of Statistics (IPS), 9th edition, by David S. Moore, George P. McCabe, and Bruce A. Craig and published by
W. H. Freeman shows students how to produce and interpret data from real-world contexts—doing the same type of data gathering and analysis that working statisticians in all kinds of businesses and institutions do every day. With this phenomenally successful approach originally developed by David Moore and George McCabe, statistics is more than just a collection of techniques and formulas. Instead, students develop a systematic way of thinking about data, with a focus on problem-solving that helps them understand statistical concepts and master statistical reasoning.
Question 1 features a randomized data table where a student selects boxplot graphs and fills in a stem-and-leaf display based on their unique set of values.
Question 2 demonstrates a scatter plot and grading for the coefficients of a linear regression line, allowing for potential partial credit.
Question 3 exhibits a tutorial for finding probabilities based on given figures displaying the uniform density curve.
Question 4 utilizes the format for a confidence interval and margin of error interpretation.
Question 5 contains the
t-distribution critical values table and directs students to illustrate values of a test statistic as a comma-separated answer list with rounding.
Question 6 showcases students entering table values to analyze data with multiple summary conclusions, illustrating an open-ended format.
Question 7 highlights multiple part questions addressing the ANOVA statistic, degrees of freedom, and approximating a
P-value using a table or statistical program.
Question 8 includes a downloadable data set for students to analyze and perform hypothesis tests.
This demo assignment allows many submissions and allows you to try another version of the same question for practice wherever the problem has randomized values.
The answer key and solutions will display after the first submission for demonstration purposes. Instructors can configure these to display after the due date or after a specified number of submissions. |
