Week 7 & 8

 Week 7 Terms:

Population- the entirety of a group that estimated by their performance

Sample- a group actually included in the study

Norming- refers to the process of constructing norms or the typical performance level of the achievement of the tested group

 Norm-reference Tests- the results are used to compare similar testers and then used to rank testers

Criterion-reference Tests- Comparing testers' results to predetermined criteria based on test knowledge. 

Validity- whether the assessment measures what is supposed to be measured

Reliability- if results can be produced under the same conditions.

Mean- average

Mode- number found most often

Median- when arranged from lowest to highest the number found in the middle

Range- differences between the largest and smallest numbers

Standard deviation- the distance score departs from the mean

In week 8 we used the terms learned to apply to sample data. We went through step by step how to apply this data to excel formatting and create graphs to be used for different purposes. Data were analyzed for outliers needing more individual reteaching or small group review. As well as being used for parent conference evidence to make individual graphs for students to be used to show parents or guardians. Through excel we could find the mean, median, and STD for given data. Also could chart which section tested was scored at what. This data was used to understand which topics were comprehended best and which need to be retaught. 

The information from these weeks will help guild our field investigation on assessment and be able to interpret testing scores. Knowing how to use excel formatting will be useful in creating a presentation to display and analyze scores found.
