Stat 445: Introduction to Exploratory Data Analysis

Project #2 Marking Results

For the most part (and not surprisingly), students did better on Midterm Project #2 than on the first project. The median was up from 66% on the first project to 75% on this project. In general, report structure and style were much improved, and I was impressed by some very clever analysis of some difficult data.

Distribution of Marks

The distribution of marks was as follows:

Project #2 grade
    histogram (median=45/60=75%)

The distributions of the individual mark components (and their correlations with the total mark) are given by the following set of boxplots. Note that, in a change from my marking for Project #1, I decided to combine exploratory and confirmatory analysis into a single analysis component.

Project #2 grade
    component boxplots

The components and their maximum possible values were:

desc (6)description of data and problem
anal (21)statistical analysis
conc (6)conclusions
open (3)open issues and limitations
level (6)level appropriate to audience
org (6)organization and structure
pres (6)presentation of analysis
clarity (6)clarity

The component meanings are described in more detail on the Marking Guidelines webpage.
