Describe and Summarise your data

Рет қаралды 52,570

Күн бұрын

If you want to learn about to summarise your data by making tables in R or provide descriptive statistics of your dataset, then this video is for you. R programming provides more than one way to summarise and describe your data. You can use base R using, for example, the table() function, for example (and that is covered in this video). I prefer to use the Tidyverse packages that make it much easier (especially if you are a beginner) to create a summary or table. So if you are into data science or just needing to analyse some data, your starting point is descriptive statistics and summary tables before you move on to inferential statistics and modelling your data. This is an R programming for beginners video and I only use datasets that you have each access to.
A huge thanks to Nested Knowledge for supporting the creation of this video. I you are doing research of any kind, you'll need to do a literature review. Nested Knowledge allows you to create and share your systematic literature reviews online. Go to: nested-knowledge.com

so far you have taught R in the best way. Please do the complete R tutorials with the aim of cracking a data analyst job. We really do not know what we need to cover as in for performing good at data analyst jobs. You can also make a video depicting an overall picture or syllabus for R, for different kind of analysis which will help us to know what all we have to learn to get a job as a DA first, and then take it from there. Please be consistent. You are amazing.

HELP! That output table you made (with the period as a name)....how do I change the name of this or export the output as a CSV. None of the normal "write.csv" functions work when I try to extract the data. The sheet just comes back blank.

I am so grateful you took the time to explain 'everything.' I paid for a course and only learned a fraction of what I'm learning with your videos. I would love to know how to change the UTC timestamp into a particular zone. I am working with a crime dataset and trying to figure out #1 what day of the week most occurred and what time they occurred. I've read numerous articles, but I need help understanding the concept. ♥

A tidyverse implementation of prop.table(table(AirBags, Origin))*100 is: Cars93 %>% group_by(AirBags,Origin) %>% summarise(number = n()) %>% ungroup() %>% mutate(propor = round (number / sum(number),3 )*100) %>% pivot_wider(id_cols = "AirBags" , names_from = Origin, values_from = propor) or even a shorter one using *count()* to replace the aforementioned 2nd and 3rd rows : Cars93 %>% count(AirBags,Origin) %>% mutate(propor = round (n / sum(n),3 )*100) %>% pivot_wider(id_cols = "AirBags" , names_from = Origin, values_from = propor)

A note regarding code at 5:03. There is a coding difference between using the |> pipe instead of %>%. If using |> , the final "summary" requires parentheses, i.e., summary(). (R version 4.3.0)
