During week 7, we learned a the basics of statistics. I reviewed a lot of vocabulary previously learned in my statistics course. With the information I learned, I can better understand assessments and grading scales. Here are a few terms that we learned in week 7...
Population- Entire group of people
Sample- group of people who participate in the study
Norming- refers to the process of constructing norms or the typical performance of a group of individuals on achievement.
Validity- Whether the assessment measures what it is supposed to measure.
Reliability- whether the results can be reproduced under the same conditions.
Mean- the average of a set of numbers
Median- The middle number in a set of numbers ranging from lowest to highest.Mode- The number that appears most often within a set of numbers.
Normal curve- A bell shaped curve that represents a set of data.
Standard Deviation- A set of data where the distant scores depart from the mean.
During week 8, we put used some of the vocabulary from the previous week to learn new things in excel. We learned how to find the mean, median, and mode just by clicking a few buttons and creating a formula for excel to solve for us. I found this very helpful for creating grade books and assessing student data. It will save me a lot of time by not having to mentally solve the problems. We also learned how to find the standard deviation of a set of numbers just by setting up a formula for excel to read. We used the set of data points to create several different types of graphs. Creating the graphs helped visually see the data set out.
