*** This project is worth 20% of total grade
Graded out of 100% and adjusted later.
Late - remember the penalty.
5% Overall report quality
ie. writing/layout/etc
90% Report:
Describe & Justify all the steps listed.
5% Data gathered is included, and clear, with consent forms.
Note: Make sure you provide all the parts requested
and justify all the answers.
Task:
** Do _this_ experiment, don't invent one!
** you should explain what speed you are measuring.
e.g. what are the units? miles per hour??
** You'll need two graphs at least to show results
You'll need to do *all* of these steps:
- Develop an hypothesis about a user's performance
with respect to the variable; 6pts
- Describe/graph that hypothesis; 6pts
** you need to have an initial hypothesis (be honest!)
explain why you think that.
Identify the type of users you'll test and why; 3pts
Determine the design of your experiment; 6pts
** i.e., what was the process used to carry out the experiment?
how was consistency maintained?
Determine the tool(s) that you'll use for data analysis &
its presentation; 2pts
** i.e., what's the stats package and graphing tool.
Develop the reading tasks that your users will perform during each
experiment; 6pts
** how many reading tasks per subject?
how was consistency maintained?
how was text selected?
was the user kept in mind?
Specify the test situation (i.e., the variations in the pages); 6pts
** what variations to actually make.
We MUST see rationale.
Determine how many users you'll need to test; 3pts
** why did you pick that number?
Select the actual users you'll test; 3pts
** how controlled?
who was eliminated and why?
Prepare the test situation; 6pts
** the web pages.
design decisions?
Do a trial run on 1-2 people to check your test
situation & procedure, and make modifications if necessary; 3pts
** how did that go? any problems & corrections needed?
For the real experiment, administer a short pre-test questionnaire
for each user to gather relevant data; 3pts
** what information was sought and why?
Have each user sign & date a
consent form agreeing to take part in the
experiment, and provide an email address at which they can be
contacted; 3pts
** This must be done.
I'll accept reasonable electronic evidence.
Describe the experimental procedure to each user in a consistent
way; 3pts
** how was consistency maintained?
Run each user through the tasks and collect data; 6pts
** how controlled?
how was speed determined?
how was comprehension determined?
Do an initial analysis of your data by providing
descriptive statistics; 3pts
** do stats look right? interesting?
Using all your data, produce graphs for your performance metrics; 3pts
** graphed properly?
Calculate the
Correlation between each metric and your
variable, and determine whether it is "significant" at the
.05 level (alpha=.05); 6pts
** done properly?
significance?
Do a
Simple Linear Regression Analysis for your data and plot the
results; 3pts
** graphed properly?
include evidence for calculation
Evaluate all the results, producing a conclusion; 6pts
** was it meaningful?
good? strange?
enough data?
was hypothesis confirmed?
Assess the possible causes of errors in the data from your
experiment; 4pts
** If anyone claims that there aren't any errors, then they're wrong!
But what errors and why?
Sum of all 21 sections = 90pts
Data gathered is included with consent forms = 5pts
Overall report quality = 5pts
Total = 100%
