man loves, as everyone should, to collect and analyze statistical information. He wishes to find a relationship between how many hours students study and how they do on their statistics tests. He takes a random sample of 16 students at Ideal U., asks how many hours they studied for a university-wide stat test and how they did on the test, enters the data into a computer for analysis and presents the results below.

A researcher is interested in hamster wheel-running activity during the summer versus the winter. She suspects that either the hamsters will run less during the winter to conserve energy or they will run more to keep warm. She records the activity of n = 25 hamsters during June, July, and August and compares their running-wheel revolutions per hour to the activity of the same hamsters during December, January, and February. The data are collected, and the results show an average difference score of Mp = 5.7 and a sum of squares of SS = 2,851.44. What is the value for degrees of freedom for this repeated-measures t test?

CCSS CCSS SMP4, 5.G.2, 8.SP.1, 8.SP.2 A fifth-grader's science fair project investigated the relationship between the length of a pendulum and the time it takes the pendulum to swing back and forth. The student made a pendulum by tying a heavy washer to a string and attaching the string to the top of a triangular frame, as shown in the diagram below. The length of the string could be varied. The table and scatterplot below show how long it took the pendulum to swing back and forth 10 times for various lengths of the string. (Several measurements were taken and averaged.)
