A research gap is a question or a problem that has not been answered by any of the existing studies or research within your field. A research gap forms a starting point for conducting further research. The purpose of a literature review is not only to examine the past available literature but also to identify gaps in the literature.

how does we know the factor scores in state?
Good video! I have a question. I am trying to replicate this analysis but with a large dataset (around 6000 respondents. The query does not run and nvivo keeps crashing. Any ideas on how to get it to work =?
When I tried to log transform in excel I have issues faith typing the log on a cell . No dropdown appears for me to choose. When I type LN nothing appears and I get stuck there. How can I over come this problem. I need your guide. Thanks.
Can I get ur contact so I can talk u
Hello Sir, I'm from indonesia. I'm currently doing my thesis research to create a new index. Your video really provides new knowledge and useful information. Thank you for this video
hey can you pls help me for the same
Thank you Sir
How do I procure an Nvivo software
Hello.. I have a question. What if your data have negative values? How can you run a log model if your data have some negative values? Thank you
Did u resolve it?
You cannot. Only positive values, numbers, items can be transformed.
thanks for simplifying this.😍😍
Thanks❤
why did you choose the covariance matrix rather than the correlation matrix?
(1). Will I have issues if I don't standardize my data? (2) Can I also directly use log values while generating my index
great work bro
How can I contact you owl

@@oluwagbangu hye tq for ur sharing. I would like to contact u as well
Thank you very useful. I want to construct an index using two-step PCA. This is the first step. Is it possible to shed light on 2 things: 1. How to carry out 2nd step when I get the results (prediction) from each dimension? 2. How to convert the result (prediction) to an index between 0 and 1
🙏
how we can I create index by PCA using SPSS
Watch out for my next video
Great video, thank you for the simple and visual video!
when entering questions do i have to put each question under variable view or put one question under variable view then the rest of questions under the data view column of question one
All your questions will be under the variable view. You take one questions at a time. After entering the question in the variable view, then you need to code your response using numbers. Then automatically, it appears in the data view then you can start imputing those codes or number in the data view
Dear Sir Thank you very much for this nice explanation. I'm waiting for your next video
Thanks for reaching out to me My next video will be out this week. I will be explaining how to analyse a survey using Nvivo Thanks
