The data are about marks and grades of a SAMPLE of students in a big course. The main variables include: Year, Gender, Semester, Mark, and Grade.

For this assignment assume that the number of ALL students in the course is much larger than the number of students in the sample data provided to you. You need to apply what have you learnt in BUSN1009 Quantitative Methods and write a report about your findings after analysing the sample data. Your assignment should comprise the following sections:

a)Descriptive Statistics use descriptive statistics and data visualization techniques such as measures of central tendency (mean, median, mode), variation (range, variance and standard deviation) and shape (box plots, histograms, frequency tables, etc.), summarise and compare data. For example, you can compare two different years or two different semesters or different genders [25% of your assignment mark, carefully read criteria for this section in the marking rubric]

b) Confidence interval estimates for the mean/proportion and/or confidence interval for the difference between two means. State the assumptions clearly [25% of your

assignment mark, carefully read criteria for this section in the marking rubric]c) Hypothesis testing for the mean/proportion and/or the difference between two

Means. State the assumptions clearly [25% of your assignment mark, carefully read criteria for this section in the marking rubric carefully]

Please note that the finished assignment should be presented as a report with the appropriate measures selected, rationale for the selection of those measures, clearly stated hypotheses and the associated tests. You will be graded based on both the statistical analysis and the quality of your writing. The assignment must be clearly written; any diagrams, charts, tables etc. must be clearly labelled and explained in your text and any equations defined and explained. Apart from the statistical analysis, you will also be graded based on your writing and communication abilities to a broader audience [25% of your assignment mark]. Your arguments and the clarity with which you explain and illustrate the relevant findings are very important.

Suggestion for the structure of the report:
