Thank you, you are indeed a genius of statistics.
@@olalekankolawole1578 thank you
thanks for the explanation! this is super helpful for my research.
but, if i may ask, what is the validity technique's name? because i know the reliability technique in this video is often called cronbach alpha. please enlighten me 🙏
in last u didn eleborate precisly how can we check our values with table
hi madam, what do I do if my reliability is a negative score? idk how that is possible but is there anything I can do?
what if we don't get significant value for validity? what do we have to do then?
Validation through experts
How do i know which all questions to be deleted from my questionnaire? If my reliability analysis is around 0.06 which is less than 0.7
Those reliability is less than 0.06must be deleted
Mam i have a one question how to check validity of test item which are choosen for my research in physical education subject
which kind of validity do we check this way? Thank you in advance
I have the sneaky suspicion that it is Criterion-Related Validity, but when in doubt, just call it validity (especially for dissertations)
I have same question
Hi Dr Gupta , During my surfing found this interesting video . Reliability well explained . Validity is not clear need more example . May i request if you have some more input on this , Pls. upload on youtube.
Sure I will explain validity how to check in our coming videos scheduled
Please upload a video related to mcq test split half reliability
Thank you!
Thank you🙏
Ma'am
If your overall reliability is greater than 9 but some construct vise reliability are less than 7 , what can be done?
If item deleted also shows every reliability above 9. What should we do?
You can either delete the item (may not be possible) or run a "reverse scale item" test. If the Reverse-scale item test gives higher reliability, then you can justify the low reliability by stating that the item was reversed intentionally to control for response bias.
Why N=100, and you test at N=40-2=38, I don't understand that
she just gave an example.
by the way You dont need to check for the crticality from a reference table. SPSS does that for you. small stars/hysterics with the values shows that the values are significant
Sorry but your accent is too strong
What do you suggest she does about it? Why be so rude?
PLEASE, Is exploratory factor analysis the same as convergent and discriminant validity? I am a little bit confused. Thanks in advance for your reply. Should we do both convergent and discriminant validity, construct validity using EFA in one study?
Me too. We can do validity per item in many variable with this method then what is EFA used for? 😅 Or is it just come into CFA without EFA?
Hello. I saw your video. You've done the reliablity test based on different variables. But, you include all variable in one measurement while doing validity. Is it allowed?
i have the same question
can i use this method in vaidating my subjective parameter grading scale.. and use in my thesis ?
How do you get the table of critical values for r persons ?
In your video there is excluded items!
Same I am facing!
How can I solve this??
Same here
mam, your communication skills are so good, i watched first vedio, which i understood properly in one go
Thank you🙏
Dear madam can u please explain what are the different ways to standardise the research questionnaire
Kindly make a separate detail vedio for validity of the data...thank you for the vedio..
Sure I will upload soon
@@Ashulekha thank you ma'am.if possible with some easy example.really it will b v.helpful...
Sure I will upload soon
@@Ashulekha thank you maam
Thankyou mam for guiding us.
I want to ask that the method used by you in this video is appropriate for Pilot study of 38 items and 41 respondents.
Thank you for appreciation yes you can but minimum responses are 50 for pilot study if you can increase this number please increase
Is the validity-checking method in this video for "content validity" or "criterion related validity"? Please let me know.
I have same Question.
more like reliability not validity
How did you select all the variables at once at 0.54 before transferring it?
Ctrl+A
Absolutely Right
Thank you Ma'am for preparing this very useful video for us. If the calculated values for Pearson's r are greater than the critical values, then each question/item is found to be a valid one. Could you Ma'am or anybody else please give relevant references supporting it?
Sure I will provide you reference
@@Ashulekha Thank you so much, Madam. You can send me the reference(s) at g_kibria@hotmail.com.
@@Ashulekha Madam, I have already found a reference that supports the use of Pearson's correlation coefficients to assess the construct validity of a scale. Reference: Laksita TB, Kloping YP, Hakim L, Rizaldi F. Translation validity and reliability of the Indonesian version of the 5-item International Index of Erectile Function (IIEF-5). Turk J Urol. 2021;47(6):489-494. doi:10.5152/tud.2021.21185
Great It will be helpful to others
@@Ashulekha Yes it will help me. Thank you.
Hello ma’am,
I’m confused between the measure to use for pilot analysis, some are using scale and some are using ordinal for likert items.
Please guide on this
Both are correct either ordinal or scale both can considered
@@Ashulekha ok thank you for the response 😊
thank you very much
Thank you🙏
Can we do this through sem
Yes we can in AMOS also
I will share link where explained in AMOS
Madam please, tell in the beginning what data is about , this is unknown for the viewers , it is questionable is it temperature, blood pressure, length, weight ???🙏🙏🙏
why u did pearson correlation, instead of spearman as your data is ordinal-likert scale
It is not ordinal data in this dataset but interval. It depends on how you treat it
Yes Absolutely Correct
hello ma is there any test to check the validity of PCA analysis
Did u find a solution? I have same problem
Thank you so much ma'am very useful and esy to understand thank you
Thank you for watching
Its just awesome thank you maam very informative session 😊
Thank you🙏
Hello Madam
Good Evening
I am very happy to have your lecture
Thank you🙏
Very nice explanation
@@naushadmujawar5401 thank you
Which spss modeler you are using mam
SPSS 24
my sister how are you,. Give me example of clothes according to coat and trousers
Thank you, the most helpful one so far!!
Thank you🙏
Kindly advice how to calculate reliability of Questionnaire if data collected is in percentage
Can you please do one for multi-response question reliability and validity please
Sure I will record
@@Ashulekha thank you very much need it urgently but thankx in advance
Correlation fails to detect loading factor. The confirmatory factor analysis is the best.
Still unable to do for multi-response questions as it is saying the same thing as when finding crohn alpha value@@bramhadianto
Thank you queen
Thank you🙏
Thank you mam ❤❤
Thank you🙏
Very useful video Madam. I have a small question. What type of validity (content/criterion/construct validity) is measured for a questionnaire by Product Moment Pearson Correlation in SPSS?
It's Construct validity. Construct validity refers to the extent to which a measurement tool (like a questionnaire) accurately measures the theoretical construct or concept that it is intended to measure. When using Pearson correlation to assess construct validity, researchers typically examine whether scores on the questionnaire correlate with scores on another measure that theoretically should relate to the same construct. This could involve correlations with scores from a similar or related questionnaire, or with scores from other established measures of the construct.
very useful for the beginner.
Thank you🙏
Thank You so much.
It's my pleasure
If the question content 3 section which section 1: liker scale question, section2: yes/no question, and section 3: multi choice question, how we can run the validity and realiability test? It’s have differend method for run reliability and validity, mem?😢
i have the same question? did you find the answer?
U have to give codes first eg yes=1 no=2. Same for multiple choice.
Madam please tell first data it is about what ??? What was the purpose and what questions were given all these things if you tell in 2, 3 minutes then it would be easy to understand the remaining part 🙏🙏
