Hello,
I am facing some doubts with recoding a factor in R. For example, if I have a categoric variable: do you eat at night? Yes, No, Other (people can write their own answer), so I get a lot of answers: some times, just in weekends, etc for "Other".
So I want to recode it in R such as an "ifelse" function. Something like that:
data$eat <- factor(data$eat,
levels=c("No","Yes", ifelse== the rest of the data),
labels=c("No","Yes", "Other"))
Is it possible?, which is the correct way to introduce the if else function?, or what can I do in order to get the same result i am expecting for?
I already tried with dyplr mutate.
Thanks in advance
I am currently facing a problem trying to merge and analyze two different datasets. I am confused about some points (maybe they could be really obvious, but those are giving me terrible headache). 1) When you merged two datasets (from same population collected at different times), how can I put together the variables?
For example, dataset1 n=100, dataset2 n=150; They have in commun variables "Age" and "Perception_index". In dataset3 (the new one), I am supossed to create the variable "Merged", where 0=dataset1, and 1=dataset2, now how should I ensamble age?, Do I need to put values in the same column (dataset1 up, and dataset2 down= 250 observations?), or on the contrary do I need to create two age variables (one variable with 100 data filled and 150 lost? and backwards).
2) when you finally have the variables, how could I compare them?, for instance, is "perception_index" higher on dataset1 or on dataset2?
Thanks a lot in advance
No normality, no homocedasticity. U Mann-whitney no significant differences, t-test significant differences, which test should I trust?
I am trying to compare categorical (male-female) on a Likert variable (0-10). I checked normality and homocedasticity assumptions, which were not achieved. Thus, I choose U Mann-Whitney nonparametric test, rejecting Ha (there are no significant differences).Nevertheles, it is supposed that t-test is potent enough to go on even if assumptions are not assumed, so I did it to compare, obtaining significant differences (same results conducting ANOVA 1-factor).Which test should I trust?
