1. How do the various types of scores differ regarding the information they provide?
Scores provide feedback to teachers and students and reflect how a student is learning, meeting objectives, and achievement level. Raw scores are actual scores calculated by the sum of total correct answers or percentage and provide criterion-referenced information about a student’s performance. Number correct scores add up the number of items a student answered correcting and interpret the instructional objectives met and overall knowledge on a subject. Percent correct scores calculate the number correct by the total number of items on an exam and give the proportion of items that were answered correctly using criterion-referenced scoring.
Subscale scoring represent a student’s performance on a single exam or across multiple assessments and can be …show more content…
Which types of graphs make it easier to understand test performance? A table is a quick way to take into account all scores and produce a frequency that lists all the scores received, the number of students who received that score, and percentage of students who received those scores. Graphs with bars representing the frequency of each score are also another way to show a quick interpretation of how a group of students did as a whole.
3. When might a classroom teacher be interested in the median or mode of test scores instead of the mean? A teacher would be interested in finding the mode when wanting to know the most common accruing score. They would use this when quickly summarizing class performance by finding the score, which most students got on a test. They would also use it at a nominal level of measurement when distinguishing categorical characteristics with gender or classroom variables. Teachers would be more interested in the median when wanting to find the score right in the middle of distribution. This is used at the ordinal level of measurement when distinguishing order, grade level, and response to intervention
