- This video demonstrates how to calculate and interpret the standard error of measurement using Excel. The standard error of measurement helps to determine a range where the true score of an instrument may fall with a specified reliability.
This video was a great extension of research. It helped me to understand the terms from that class better, and made it less complicated.
Since we do not know what the true scores will be for each participant then calculating standard error of measurement is a good way to guess the chance of the true score falling between upper limit and lower limit. The video was easy to follow and the example was easy to understand and apply.
+Michelle Robinson For sure. These are helpful measurement tools.
Calculating and Interpreting the Standard Error of Measurement using Excel is a great video in finding out and interpreting the true score and standard error of measurement by knowing the probability of the confidence interval. I didn’t realize that 95% was the main goal. How well an instrument can produce accurate results seems to be the basis. This information can be helpful in observations, research, and having statistics that can measure the data. Finding the upper and lower limits and the Z scores was helpful to see through excel. It’s interesting that all of these formulas can enable the data to be interpreted.
What actually stood out the most for me was the Intraclass Correlation Coefficient. The video states that this Standard Error of Measurement function is used for either Cronbach's Alpha or the ICC, but the ICC is specifically used for paired data. I'll be watching the video on the ICC next!
Standard error is great to learn how far we are away from the true score. It basically is a statistic that allows to see how well an instrument yields results. Great video!
+Toniette Morda The standard error is really important when it comes to tests and assessments. I can understand how and why it would be used. I thought it was a great, informative video.
I liked that this video gave an explanation on how to interpret the standard error of measurement I liked the visual element this video had, it made it easy for me to follow and better understand.
Helpful tools and helpful ways to calculate these scores and values. Statistics would be so difficult without Excel and SPSS!
This video is easy to follow and is helpful in understanding the upper and lower limits.
This video was helpful in understanding how to determine the standard error of measurement and clearly explained how to calculate the upper and lower limits in order to determine where the true score will most likely fall. Overall, fairly easy to follow.
+Jacklin Skibicki I agree, this video was easy to follow. I also thought it was very helpful in understanding how to interrupt the standard error of measurement.
+Jacklin Skibicki I agree, fairly easy to follow. I also appreciate the explanation how to calculate the upper and lower limits where the true score would most likely fall. This was a bit confusing in the beginning.
This was a good video and easy to follow, I find it very interesting that although we can conduct such calculations to interpret the standard error of measurement, the true score is not exactly known.
I feel that I am slowly beginning to understand what Dr. Grande is teaching. I have a difficult understanding this kind of material, or anything related to math, but I feel like with the books and videos I am getting better.
Very similar to the confidence interval video. This was a nice video to follow the easy steps to figure out the chance of a true score.
This was similar to the confidence interval video, which was nice. Many of these terms I never fully grasped in research, but I'm starting to understand them much better now.
+Rachel Foster I feel the same way Rachel. Slowly I am beginning to understand
+Rachel Foster The repetition is definitely helpful. What was overwhelming last semester is now starting to come together for me.
This seems quite similar to the confidence interval. I again liked the color coded boxes. It helped me to follow along better and understand the concept. What I'm a litle confused on is why you would use this over a confidence interval. Maybe I missed that on the video.
+Mandy Moore The color coded boxes really do help keep things organized and easy to follow.
+Candace Fernandez Yes, the visual instruction and organization of this video is very helpful.
Very straight forward, very easy to understand, perfectly logical.
I agree, Dr. Grande explained this well.
The video was straight forward and the examples do help with making it easier to relate to real life.
Do you have the link for your video showing how to calculate the reliability you mentioned in this video. I must have overlooked it. I am using SPSS currently and learning these functions and terms. I appreciated seeing the excel version using formulas because I am able to connect the dots better. Thanks for making this video.
Thanks for the video - are the 50 scores from one person taking the test 50 times? what are the least amount of data points you would need from one individual to calculate the SEM?
Love this visual aid!
Standard error of measurement = SD * square root of 1 - Reliability (and the reliability is something you manually enter depending on the situation, i.e. Cronbach's Alpha or ICC)
Thank you sir, It will be very helpful for me.
Having just watched the video on calculating the 95% confidence interval, this looks very similar. The concept is similar too, calculating the range the true score falls into instead of the mean. What strikes me is the amount of information you can get out of a set of data on excel.
+Alicia Zahn Yes! You can get alot of info from this set of data!
+Alicia Zahn Yes! You can get alot of info from this set of data!
+Alicia Zahn I found it helpful that I had just watched the previous video. The concept is very similar and the out put of information is great.
+Alicia Zahn After watching the previous video this was familiar and easy to follow.
I think its interesting that although we can conduct such calculations to interpret the standard error of measurement, the true score is not exactly known.
For me, this would be more straight forward and helpful if I had a slide that shows the formulas in the grey blocks instead of the numbers. I do not have all of these memorized nor will I probably ever have them memorized, but if I had something that had formulas available for each of the blocks I could visually figure out what numbers or codes to use to get the results.
+Bethany Elstrom That would be a good idea. Then we could look at what is happening while the calculation is going on.
I agree great idea! It would be nice to see the formulas as well.
please Dr can i have your email i have something to discuss with you with regards an examination score
