    Thank you this was a easy to follow tutorial to get into R studio. - I don't find the syntax mistake though I'm not sure there is one. for the last plot: plot(data1$Risk.Taking, data1$Opportunity.Evaluation, main ='Scatterplot of Risk Taking and Opportunity Evaluation', xlab='Risk Taking', ylab='Opportunity Evaluation') I get a scatterplot but Risk Taking on the x-Axis is scaled: 4.5, 5.0, 5.5, 6.0, 6.5 and not 0, 20, 40, 60, 80, 100

    Hello, I've come across this video of yours, can you suggest the best way in finding out the results with this SOP of mine? SOP 1 - Finding out the demographics of the students pertaining to their sex. SOP 2 - Identifying the final ratings of 2nd year nursing students in all of their NCM lab subjects pertaining to return demonstration activities. SOP 3 - Is there a significant relationship between the academic laboratory performance of nursing students with their demographics? SOP 4 - To carry out the Output and Recommendations after conducting the study. THANK YOU!

    What do you mean here by "stress", performance" etc words? Do you know how we can replace them in our cases? I have 5 treatments (independent variables) and multiple dependent (response) variables. 1. How can I do ANOVA at the same time for all groups and for the whole dependent variables? 2. How can I do treatment mean, SD/SEM for each treatment group? 3. How can I give superscript letters for significant treatments/groups for each response variable? Thank you for your help.

My research title is about Factors influencing Purchase Intention and I've seen a lot of related studies that uses likert scale data which is then analyzed via Multiple regression. I hope you can help me with this problem... How can I use the likert scale data for multiple regression analysis?

    Hi. Thanks for this video. Posible po bang gamitin ang Pearson in correlating likert scale data? I have seen readings that do not recommend it and instead suggest using Spearman. However, I'm not really familiar sa Spearman and hindi siya available sa Excel. I already have SPSS but i am not sure how to do Spearman using it so I'm thinking na if kaya naman pala ng Pearson, I'll just push through with Pearson. Hoping you can respond. Thank you!

    • @raffycee6403
      @raffycee6403 2 ปีที่แล้ว

      Hi Cherrie.. Some researchers use Pearson for Likert scale while others suggest Spearman. For as long as your decision is supported by literature, there is no problem with it.

How may the respondents describe in terms of: 1.1 SEx 1.2 Year level, and 1.3. Strand? 2. What are the factors that affect the students' performance online class? 3. Is there a significant difference on the factors affecting the academic performance of the students in online class when they are grouped according to profile?

      Hi Jah.. You may want to consider Frequency and Percentage for SOP1. For SOP2, how are you planning to answer this? Do you have identified possible factors that may affect students' performance? If so, you may want to check regression analysis (multiple linear regression) for this. For SOP3, this is not clear to me also. What are the possible factors that you are considering?
