These are my answers to Question 4 and Question 5 for Friday, October 21, 2011. I used a clustered column bar graph in Excel to determine the results of Level 1 & 2 Reading for Grade 11.
In terms of the most peaked on the clustered column bar graph, I noted that Category 8 (Special Education) in Level 1 had the highest peak at 67.94%.
In terms of the least peaked on the clustered column bar graph, I noted that Category 1 (Asian) in Level 1 had the lowest peak at 11.86%.
In the clustered column bar graph, I noted a unimodal score in the distribution due to the fact that a unimodal distribution was observed, which had one peak or "mode." When I look at this distribution there is definitely one score that is higher or occurs with a higher frequency (Category 8), which I feel shows that this distribution is unimodal.
The clustered column bar graph located below reflects the results of Level 1 & 2 Reading for Grade 11:
