This practice exam is 24 points, so it should take 36 minutes. Remember to look at how many points each question is worth! In a three-point question, you should provide three pieces of information. Don't waste your time writing a paragraph for a one-point question.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 16.25px;">With a quiz and a cumulative exam approaching, I wanted to make a list of all the concepts we covered in our first unit on statistics. Remember that we will be testing you on conceptual knowledge (i.e. Why does a biologist use a t-test?) instead of mathematical knowledge (i.e. Calculate the p-value for the following data set).

**List of concepts in statistics**

 * Type I (false negative) and Type II (false positive) error
 * Probability / p-value
 * Confidence level (α)

I realized that some of the stuff about action potential is hard to understand! So I made an animation that you can move through step-by-step to help you understand.

Your task (assessed on Criterion D) is to create a poster that highlights some of the issues. You will show the strengths and weaknesses of the news article that your group has chosen. Follow the instructions in the rubric and make sure you read the "descriptors" to see how to earn a good grade. <span style="font-family: Arial,Helvetica,sans-serif; font-size: 16.25px; line-height: 0px; overflow: hidden;">

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 16.25px;">As a scientist (or a well-educated 10th grade CCB student), seeing science in the news can be a depressing experience. This video [|Scientific Studies: Last Week Tonight with John Oliver]does a good job addressing the issue. The only problem is: How do we tell good science from bad science? Good reporting from bad reporting? We're going to use what we learned this unit to critically assess some selected news releases.

This is a fun and accurate comic about Science and the media.

We've heard you loud and clear. You don't like statistics! Well guess what? One prominent psychology research journal doesn't like them either. They completely banned p-values from being used in their research! Read about it here: []

What do you think? Can we do science without statistics? summarize the problems with p-values in modern science. Research at least 3 alternatives for p-values.

Nuzzo, 2014 provides a nice background information about p-values in Natural sciences

[|P-values Under Fire] : This link describes the current controversy around p-values.

In your first graded assessment of the year, you will apply what you have learned about statistics to make a conclusion to an experiment. Find your personalized data set in the following file: Then follow the instructions in the rubric. Pay attention to the necessary elements required to obtain the grade you want.
