This statistics project makes up 10% of the final course grade for MATH 14, Statistical Methods. The purpose of the project is to give you hands-on statistical research experience where you work with real data that you have collected. PROJECT GUIDELINES The project will be limited to hypothesis tests outlined in Chapter 8. This means that the claim you will be testing will be related to a single population (not two populations as described in Chapter 9). After you choose the idea for your project, the basic steps will be: 1) Forming a research question and stating the question as a claim to be tested with a hypothesis test. Note: Your exact claim might be formed AFTER you collect the data and do some preliminary analysis. 2) Collecting the appropriate data. 3) Calculating the various descriptive statistics necessary to describe the data and using them to carry out the hypothesis test. Choosing a project: To perform a hypothesis test, the most essential element is a claim about a population. The quantity that you wish to make a claim about should be something that is measurable with: a) A ruler or tape measure (to measure length). b) A scale (to measure weight). For example, depending on the size of the objects you're weighing, this could be a postal scale or a bathroom scale. A clock or stopwatch (to measure time). Your hypothesis test will be created directly from your claim. Your claim must be about the mean (u) or the standard deviation (a). Do not use a claim about a proportion (p). Also, do not include in your claim. Whatever you choose to measure, whether it's a length, or a weight or a time duration, the quantity must be a random variable. That is, it must be a quantity that is determined by chance. Here are some simple project ideas: 1) Find some public land with a lot of the same type of cholla cactus. Take a sample that consists of measurements of the heights of the cacti and make a claim about those heights. (Always use caution when working in wild places, being careful to avoid injury from plants, animals, and insects. 2) Observe a busy road intersection with stop signs and measure the amount of time cars are stopped before moving through the intersection. (Always observe from a safe location and one where those being observed don't know they're being observed.) The possibilities are endless! Remember: most of the hypothesis tests we study require that more than 30 values must be taken in your sample; some tests require that the data be normally distributed. You should try to collect your data in a random way. Ideally, you'd like your data to be a simple random sample. Necessary Elements of Your Project Report: 1) A table of your data values." 2) A histogram of your data. 3) A normal quantile plot of your data using Statdisk (this is one of the analysis tools available at https://www.statdisk.com and was written by M. Triola). 4) State the value of any necessary descriptive statistics such as n, x, and s. 5) Give your claim in words and as a mathematical expression. 6) State the null and alternate hypotheses. 7) A neat hand drawing of the appropriate distribution for your hypothesis test showing the tail(s), the critical value(s) for a traditional hypothesis test (state the significance level), and showing the location of the test statistic. Do not use Statdisk for this. 8) Give the equation you used for the test statistic with the numbers in place, and the test statistic's numerical value 9) State the p-value associated with the test statistic. Use technology to get the p- value; do not approximate the p-value using the distribution tables. 10) The conclusion of your hypothesis test for the null hypothesis and your claim. Note: You may expand this list if you wish, but be sure to give the elements listed. Present your project as a report with an opening paragraph that explains what was done. Give each element listed above in the same order as listed. Give a concluding paragraph that says what the final findings were. Please write neatly and clearly if you don't type your report. You may use Statdisk or other computer graphing applications for all graphs except the graph of the distribution in (7) above. For graphs drawn by hand, please draw them neatly on graph paper, or on a grid carefully made with a ruler. Criteria for Grading the Project The project will be evaluated using the attached score sheet. Restrictions a) As mentioned above, you may not do a hypothesis test for a proportion, p. b) You must get your own data - you may not use data from a website, or other source, and the quantity must be measured as described above.
