Our research teacher only gave us 5 hours to submit our Chapter 3. And this is the first time that we're introduced to different statistical methods... She didn't discuss anything about research. Didnt even provide the basics. So thank you for this.

Sir, thank you very much for this video. Your method of presentation makes it easy for beginners like me to understand the concept. The step-by-step process using a sample set of data makes your explanation highly comprehensible. My deepest gratitude, Sir for simplifying this complex topic. Your voice is also soothing and gentle, easy on the ears.

🎯 Key Takeaways for quick navigation: 02:25 🔢 Kuder-Richardson Formula 20 (KR20) is used to measure the reliability of a test with binary variables, such as multiple choice or true/false questions. 03:32 📊 KR20 results range from 0 to 1, with values closer to 1 indicating higher reliability and values closer to 0 indicating lower reliability. 11:35 📈 To calculate KR20, you need the number of test items (k), the summation of pq, and the variance (s squared). 15:49 🧮 KR20 can be calculated using a formula in Excel or manually with a calculator, following specific steps. 19:33 📚 A high KR20 value (close to 1) indicates a very high relationship and suggests that the test has high reliability.

Hello sir. I am very new at this and struggling to learn. But I just want to ask things regarding the pq. When 0.67 is multiplied by 0.33 manually, it appears that the product is 0.2211. similarly, when 0.48 is multiplied by 0.58 manually, the product is 0.2436. My question sir is, should I take up to the hundredths place without rounding it off? 0.2211 became 0.222, while 0.2436 turned just to 0.243 . I'm a little bit confuse sir in the part that 0.2211 must only be 0.221, and 0.2436 must be 0.244 since the next number is 6 which supposedly a round up.. I hope you can notice my comment as I badly need help. Sorry for grammatical errors as I am don't speak English good.

Hi, thanks for asking. The rounding off and all calculations are done in MS Excel, not on your calculator. What you see on each cell are decimal numbers that were only rounded off to 2 or 3 decimal points. So it is possible that say, for example, 0.75 is actually 0.754567897686576.

Hi sir! I just wanted to ask my questionnaire is based on yes or no questions with some questions are calculated for correct answers and some questions are just for response based......so do i apply kr-20 for all my questions.....and then i have 2 different sections which assess 2 variables......so each section i need to do kr-20 separately is it
@glentox1563
@glentox1563 2 года назад
Hi, thanks for asking. Yes it would be good if you test the relationship of each section using KR-20.

Hi, you may want to try this. On you excel file, press "CTRL F" and click replace tab. Then you can replace all cell with "true" value to 1. Repeat the same procedure with "false" value to 0.

Thank you for the video. I would like to know can we use both cronbach alpha and KR-20 in the same study? since i have nominal, dichotomous and likert scale questions in my questionnaire. Should i only use KR-20 for the three types of items? or use KR-20 for nominal and dichotomous items and cronbach alpha for the likert scale items? Waiting for your reply. thanks
@glentox1563
@glentox1563 3 года назад
Hi, thanks for your question. Basically, KR20 and Cronbach's alpha is the same. Cronbach's alpha is the extension of KR20. KR20 works only for dichotomous measures while the other works with polytomous measures. You can apply KR20 for your nominal dichotomous measures (with binary coding say for example 1-yes and 0-no) and Cronbach's alpha for the likert scale questions. But even if you apply/use Cronbach's alpha on dichotomous measures, you will notice it yields same result because the formula is just the same.

Hi, thanks for asking. The highest possible value for KR20 is 1. There must be an error in your computation if you have a result of 1.01.

I think you should use the VAR.S formula instead of VAR.P since a test is a sample.
