Normality testing in Jamovi
Переглядів 1613 місяці тому
This video shows how to generate Skewness, Kurtosis, and Shapiro-wilk statistics, and how to interpret them. These statistics are very important since they show whether data are normally distributed or not, hence researchers would know which statistical methods to apply on the data while answering their research questions.

This video shows how Ms Excel can be used to select a simple random sample from a large data set. Processing is always slow with large data sets, hence researchers need to learn how to select random samples from master databases.
Excel: One-Way Repeated Measures ANOVA
Переглядів 983 місяці тому
This video is about repeated measures ANOVA for a single factor using Ms Excel. This statistical test is conducted if there are more than two related groups whose means are to be compared. Use ANOVA single factor without replication since Excel doesn't not have a command for repeated measures.
Using Excel to Perform a One-Way ANOVA test followed by a post-hoc test (Bonferroni correction)
Переглядів 1023 місяці тому
When your ANOVA results are significant, you need to follow it up with a post hoc test in order to determine which groups have significant differences. But if you don't get significant results from your ANOVA, no need of post hoc test s

Excel: Simple Linear Regression (SLR)
Let's learn how to run a Simple Linear Regression in Excel... Beginners, let's gather here.
Let's gather here and learn how to create dummy variables for a categorical variable. Remember categorical variables have to be dummy coded before including them in a multiple regression as predictors.
Let's gather here and learn how to select cases in SPSS.
Well explained. Thank you. I will also check the previous video so that I get it all.
@@StatisticianDataanalyst-y2k Ok, welcome
Let's gather here and learn how to run chi-square test of association using jamovi, and how to interpret the results.
Normality testing of data is important because it determines which statistical methods to apply on your data. Students/researchers/scholars let's gather here, watch this video and learn how to test for normality using jamovi software.
Kurtosis < 3 does not indicate " too flat". There are distributions with kurtosis<3 that are infinitely peaked. Also, kurtosis>3 does not indicate "too peaked." There are low, perfectly flat-topped distributions with very high kurtosis. Examples of such distributions are given on the current Wikipedia page. Kurtosis measures tail weight only.
@@peterwestfall6924 Wikipedia is never considered a trusted source and is never used by Universities and other higher learning institutions. Please buy and read the book "Mathematical Statistics with Applications" by K.M Ramachandran & Chris P. Tsokos. You will learn more about Skewness and Kurtosis in this book.
Most companies are becoming data-driven, and are making evidence-based decisions, and so data analysis knowledge is much vital. Let's learn it guys!
For me, SPSS is the easiest.
@@StatisticianDataanalyst-y2k ok, but learn the rest as well
Thanks alot 🙏. Now I know how to interpret skewness and kurtosis. Before I only knew how to interpret Shapiro-wilk results.
Nice, now you know 👍, keep practicing.
Can you explain to me more about skewness and kurtosis? This is what gives me headache to understand.
Yes, watch it in my next video 👉👉
Now I know how to generate descriptive statistics in jamovi, and how to interpret them. Thank you!

Perfect explanation, thanks
Yes, make sure you watch and learn from it.
⭐⭐⭐⭐⭐
Thank you.
