Question

This project gives you the chance to use all of the statistical techniques and concepts that are covered in the initial chapters of the text. Problem: Think of a question that can be answered by analyzing data. Data Collection: This is an open ended project and you have wide latitude as to what question you would like to answer and where you get the data to answer the question. Guidelines/Restrictions:  Your data should be numerical and continuous.  You should have at least 30 observations or data points.  You may use either sample data or an entire population.  You may gather data though experimentation or you may use published data. Project Requirements  Project Introduction/Summary You are to write 1-2 page report to include the following:  An introduction which includes:  The question you want to answer  What information you analyzed and where it came from  What analysis of the data you have done  The answer to the question you posed  A complete description of the data to include the description and interpretation of:  The three foremost measures of central tendency  Variation in the data, including range, quartiles, interquartile range, standard deviation and variance.  The shape of the data (symmetry and skewness)  A comparison of the data with what is predicted by the Empirical (normal) rule and the Chebyshev rule. You should conclude as to whether or not the results you got are what you expected and why or why not.  A summary and conclusion that ties back to the introduction. You should specify which parts of your analysis support the answer to the question you posed in the introduction.  Required Supporting documentation  Appendix I: A photocopy of original data  Appendix II: A frequency distribution table and histogram (FROM EXCEL)  Appendix III: A table with the mathematical measures of central tendency and variation (DESCRIPTIVE STATISTICS SUMMARY FROM EXCEL)  Appendix IV: A chart comparing expected and actual results when applying the Empirical (normal) rule and the Chebyshev rule The report should be typed using a word processor (single spaced, 12pt font). All calculations and graphs should be prepared using Excel.

To find out the average height of girls and boys studying in X std a survey was conducted.  A particular school was taken with 500 students in X class. From this, a random sample of 30 boys were taken.
The data is given in the excel sheet.  Height is continuous and boys are almost of the same age as they study in the same class.  The samples were purely drawn at random in such a way that the role numbers were drawn at random to select the 30 boys.  The height was a continuous variable here.
Here we have selected one particular school and a random sample of 30 was taken.
