Define the terms **standard error** and **standard deviation**. Then, using a hypothetical example _not in the textbook_, describe a situation in which you could compute the two, and highlight how they are different (hint: your answer should include a description of how to generate a **sampling distribution**).

4. Calculating the standard deviation and the estimated standard error for the sample mean difference Aa Aa A researcher is interested in hamster wheel-running activity during the summer versus the winter. He suspects that either the hamsters will run less during the winter to conserve energy or they will run more to keep warm. He records the activity of n = 16 hamsters during June, July, and August and compares their running-wheel revolutions per hour to the activity of the...
