MATH 2050 Project Guidelines
Your grade will be determined by the paper you hand in and the presentation you give.

Your population of interest will be all MTSU students.
For the simplicity’s sake, we will use our class as our “random” sample.

Your tasks:

Data Collection:
•Determine 4 to 6 variables (at least 2 quantitative and 2 qualitative) you would like to collect information on from the sample. •Write a survey that asks clear questions that will allow you to collect your data. Type this survey up in (with your name somewhere at the top) and print 45 copies.

Research Questions:
•Write at least 3 research questions about the population that can be answered from your data. Two or more of these questions should be able to be answered by a hypothesis test (these questions will investigate relationships between variables) and one or more could be answered from a confidence interval (this question will investigate the true value of an unknown parameter).

Data Analysis:
Conduct appropriate data analysis techniques to answer your research questions. This analysis should include two or more hypothesis tests, can include one confidence interval, and should include at least one graph. (If you don’t do a confidence interval, you should do at least 3 hypothesis tests.)

Paper:
Write a paper that includes the following:
•An introduction that gives an overview of the big idea of your project and the research questions you sought to answer •A methods section that clearly states your methodology (what data did you collect, how did you collect it, and how do you plan to analyze it?) •A results section that clearly states how you analyzed the data (clearly report the results of your data analysis… include graphs and tables where necessary… give the specifics of the results of your data analysis here (p-values, etc.)) •A conclusion section that discusses how your data analysis informed your research questions. Include limitations of your...

...Hypothesistesting
Use of hypothesistesting can be very useful during decision-making connected with statistical data. A hypothesis is a statement made about a population parameter e.g. a mean and variance of a population. Hypothesistesting is a statistical process, which gives ideas or theories and then determine whether these ideas are true or false. The conclusions in...

...understanding of hypothesistesting. The textbook explained the aspects and steps of hypothesistesting in a legible fashion, while the video helped demonstrate a real-life application.
I learned from the text that hypothesistesting is a “Procedure for deciding whether the outcome of a study (results from a sample) supports a particular theory or practical innovation (which is thought to apply...

...Elements of a Test of Hypothesis 1. Null Hypothesis (H0 ) - A statement about the values of population parameters which we accept until proven false. 2. Alternative or Research Hypothesis (Ha )- A statement that contradicts the null hypothesis. It represents researcher’s claim about the population parameters. This will be accepted only when data provides suﬃcient evidence to establish its truth. 3. Test Statistic - A sample statistic...

... The assumptions of ANOVA are identical to the t-test and the calculated statistic is called an F-value which has a probability value associated with it. As with the t-test, if our probability value is less than 0.05 we reject our null hypothesis (in this case that there is no difference among the treatment groups). This p-value only tells if there are significant differences among our groups. It does not tell us where these differences are. In other words, in an...

...HYPOTHESISTESTING
WHAT IS THIS HYPOTHESIS????
• In simple words it means a mere assumption or supposition to be proved of disproved.
• But, for a researcher it is a formal question that he intends to resolve.
• Example: I assume that 1) under stress and anxiety a person goes into depression.
2) It leads to aggressive behaviour.
Eg. : Students who get better counselling in a university will show a greater increase in creativity than students...

...HypothesisTesting For a Population Mean
The Idea of HypothesisTesting
Suppose we want to show that only children have an average higher cholesterol level than the national average. It is known that the mean cholesterol level for all Americans is 190. Construct the relevant hypothesis test:
H0: = 190
H1: > 190
We test 100 only children and find that
x = 198
and suppose we...

...CHAPTER 4 – THE BASIS OF STATISTICAL TESTING
* samples and populations
* population – everyone in a specified target group rather than a specific region
* sample – a selection of individuals from the population
* sampling
* simple random sampling – identify all the people in the target population and then randomly select the number that you need for your research
* extremely difficult, time-consuming, expensive
* cluster...

...Nonparametric HypothesisTesting Paper
ABC’s real estate agency has recently expanded its business and is in the process of conducting research on housing prices within 10 miles of its new office. Team B has been given the task by ABC real estate to conduct the needed research. The team will be able to answer at the end of the research if the prices in Santa Cruz, California, are less than the prices of house in Scott’s Valley, California. Throughout this research...
