Midterm Individual Project.

Instructions:

1. Please limit your analyses and discussions to the variables listed.
2. Your page limit is 10 pages. Output to support your answers should be attached at the end of the project and does not count toward your page limit. The only exceptions to output embedded in the project are histograms. These should be embedded within the project where they are requested. Anything beyond page 10 will be considered supporting documentation and will not be graded.
3. Tables should be produced in Word or Excel, and transferred into Word, with all values, except test statistics and p-values, rounded to tenths. Credit will not be given for summary tables produced in JMP/epi info and pasted, as answers, into this project.
4. You should use exact p-values to determine significance. (Hurray, no tables!)
5. Please frame your project according to template provided. Each question should be answered as numbered.
6. Do not change variables (categorize) unless specifically instructed.

Scenario. You’ve read several articles about the association of birthweight (BWT) and intra-ventricular hemorrhage (IVH) after delivery , but you would like to look at it in more depth. You decide that you have a novel approach to looking at it and a datasource, so you put together a study.

Your research question is: Is there an association between birthweight and intra-ventricular hemorrhage?

You will also be looking at the following covariates (additional independent variables):

Gest: Gestational age

LOL: Duration of labor

Pltct: Platelet count

Delivery: Delivery type (vaginal vs. c-section (abdominal))

Sex: Gender of baby

Twn: multiple gestation

The codebook and data are attached.

Your mission: Plan and execute the first part of your study based on the information and data you are given.

You should include the following:

Hypotheses.

1. Your null and alternative hypotheses in text format and in symbols.
   Methods.
   General
2. information on your dependent and independent variables, including covariates:
   1. whether they are continuous or categorical
   2. What their levels of measurement are
      Description
3. What univariate descriptive statistics you plan to produce and why. All variables should be discussed.
4. What bivariate descriptive statistics you plan to produce and why. All variables should be discussed in reference to your independent and dependent variables .
   Planning for inferential stats
5. Your alpha level, what it means and why you choose it
6. A discussion of type I and type II error and how you think they might impact your project
7. A discussion of whether you will use one-tailed or two-tailed tests and why.
8. Analyses
   1. Based on your research question and hypotheses, what test will you use to examine your dependent variable and your primary independent variable? Why? (Hint: think number of levels and levels of measurement). Run this test.
   2. You want to examine differences in birthweight, LOL and platelet count by multiple gestation (twn). What test do you use? Why? Run the test for differences in birthweight only.
   3. You also think that you might have collinearity (correlation) between Gestational Age and birthweight. How will you test this? Why? Run this test.
      Results.
9. Univariate tables (completed)
   1. A brief discussion of your overall sample based on your univariate tables.
10. Histograms of any continuous variables along with a short description of the distribution(s) including information on skew, modality and kurtosis.
11. Bivariate tables including statistical test results and p-values (completed)
    1. A brief discussion of your overall sample based on your bivariate tables.
    2. Discussion and Interpretation of your statistical results ( only include tests conducted through module 3)
