Assessment Data Reporting Techniques Joe Slowensky, Jennifer Waldeck, Nina LeNoir, and Steve S. Lee May 1 st, 2013

Goal – To create simple visual representation of data

Overview Setting up a data file o Transferring data from collected rubrics to database o Coding the data from the rubric o Handling multiple reviewers Calculate percentages o Creating numbers to report Creating Charts

Transferring Data From Rubric…

To A Data File.

Coding the Rubric Data Four possible ratings on each learning outcome o Not reflected  0 o Minimal  1 o Proficient  2 o Advanced  3

Setting up columns and rows in Excel Row = one student, Column = learning outcome

Handling Multiple Reviewers If there are multiple reviewers, guidelines must be created to reconcile different scores and reach a consensus.

Calculating Frequency Percentage Instruction Video h?v=c6w4m3JMNHM h?v=c6w4m3JMNHM Enumerate all possible answers Create a new column next to your original column Highlight original column, go to “Data” tab, click on “advanced” in the “Sort & Filter” Section. Select “Copy to another location” and “unique records only”. Copy to: click on selection box (see red circle) and then highlight the cells where you want the data to appear.

Calculating Frequency Percentage In next column, type “COUNTIF(“ and the select all of the cells in the original variable. The cell numbers will appear in the formula “COUNTIF(M2:M61”. Continue by typing a “,” and then select next column of numbers enumerating the different possible outcomes “COUNTIF(M2:M61,N2:N9)”

Calculating Frequency Percentage Copy and paste the finished cell to the rest of the value. Calculating percentages for each category is now possible.

Creating Charts Highlight numbers in chart. Go to the “Insert” tab and then click on the down arrow near the pie option (see picture). A drop down box of pie options will appear. Pick one. Chart options can be changed under the “Design” tab, “Chart Layouts.” Clicking on the option circled in red will insert raw numbers and percentages into the pie chart.

Charts

Population and Sample Size For programs under 1000 students, you need to collect data from 30% of your total population size. o Please remember small populations are volatile and small increases in sample size produces large gains in accuracy.
