Demo 7 Questions- Group 2 by Chaudhuri, Saswati https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt Please add the questions that you may have on your mind related to the final assignment and course content so far. en-us 2021-04-28 09:23:22 UTC 2021-05-03 08:04:49 UTC hello@padlet.com Reporting N alkhidr https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1473561748 When reporting N in the APA style tables: do we mention the N with or without the missing values. So if we have overall 100 entry of 100 participants but in Variable X there were 10 missing values. So should we report the N=100 or 90? ]]> 2021-04-29 13:10:10 UTC https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1473561748 When doing the normality test https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1473615107 if for the same variable, the P value of kolmogorov and Shapiro are different, so one of them is less than 0.05 and the other is more than 0.05. What should we consider our data: normal or non normal?]]> 2021-04-29 13:20:08 UTC https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1473615107 the Independent Samples t-test https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1474048393 this tests: A comparison of the two groups’ averages (mean)

So if a question says: 

Is there a difference between men and women in the X variable?

We Must calculate the mean of this X variable first then do the T-test? Even if it is not explicitly said in the question that we do the mean of X ?

When reporting: should we put the table or we just report by text?]]> 2021-04-29 18:32:31 UTC https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1475346787 Is (read1) variable ? https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1475654033 mean scores of the literacy sum score 

OR just

the literacy sum score ]]> 2021-04-29 19:44:20 UTC https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1475654033 Testing the Normality https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1477632797 Before we run a T Test or an ANOVA  test, we need to test the normality. Do we have to test the normality of only the dependent variable or also the independent one?  
2. Do we have to calculate the descriptive statistics (mean, median, SD...) every time and illustrate the main values in the table?]]> 2021-04-30 11:03:38 UTC https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1477632797 Chi-square tests https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1477637880 When we run a chi-square test, do we illustrate the results in a text or also in a table? ]]> 2021-04-30 11:06:33 UTC https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1477637880 Final assignment https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1477642636 1. For the final assignment, if we test the normality and the data is not normally distributed. Do you expect us to delete the outliers to try to use a parametric test or not? 

2. The instructions say that we have to illustrate the interpretations/conclusions, what do you mean by this? Is it an extra paragraph apart from the results' text? 

3. In the first exercise, do we have to create a chart with excel and calculate the frequency distributions?

Is this right? https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1478572927 So like gender variable, it only contain to values either male or female so it could not be normally distributed?

]]> 2021-04-30 15:06:46 UTC https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1478572927 Variables Types https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1482779099 I am very confused about variable types. Sometimes a variable is continuous but in other times it is considered categorical. This makes me cannot decide the right test.

Do you mean the way that is written in the slides? or are there certain standards we should know about. Because I think not everything is written in the slides, I mean there are things that we may need to report that are not specified in the slides.]]> 2021-05-02 17:54:04 UTC https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1482818481 Mean Scores of variables https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1482853918 I am always confused when reading the text of the questions when it is referring to the mean scores of variables M that we calculate by doing descriptive statistics

AND

The mean scores of variables that we calculate Z  values and then the mean using the Z values. which is the mean of many questions that are measuring the same thing.]]> 2021-05-02 18:16:50 UTC https://padlet.com/saswatischaudhuri/xu5ek3kze5emarkt/wish/1482853918
