Using the the ggplot2 R package to create a boxplot with individual data points overlayed (CC091)

A boxplot shows the median of a distribution along with the 25th and 75th percentiles as well as an indicator of which points are outliers. In this episode of Code Club, Pat will use ggplot2 with the geom_boxplot, geom_jitter, and stat_summary functions to create a boxplot with the individual data overlayed on the figure.

Do you have a figure that you would like to receive a critique or help improving? Let me know and I'd be happy to arrange a guest appearance!

What do you think of adding a boxplot to a jitter plot without including the whiskers?

[TheSandrao]

Absolutely love your videos! Keep up the great work

I would have thought it was a 95% CI, so I learned something there.

[cyrillejar]

Really interesting !!! Many thanks !
I think I will use jitter plot with box plot for my next analyses. But I will keep the whiskers, without you miss the extreme values ... I'm not sure it is really important to explain the 1.5 times about whiskers, I think it is enough to say that above or below we consider the values as extreme.
Thanks again, even if do not agree for whiskers I really appreciate your point, an I always learn new things !

Hi Pat, does the position of the jittered points change each time you run the code or itmust be fixed at each code-run?

[KN-txsd]

Hi Pat, is it possible to pin the number as you have shown for the x-axis labels for the Titles and subtitles, and captions. Thank you

[KN-txsd]

Hi Pat, is it possible to reduce the space between the two x-labels so the plots are near to each other.

Hello!! can i get a sentence for drawing Boxplot without min and max? just a box without a line!
I know you explained it but English is not my first language so it's kind of hard to understand the whole thing...

how to do Box and Whisker Plot in R?? Please Urgent 🙏😭

[valerierussell]

Yeah, I thought the whisker was the entire range....

[mdmominulislam]

is it possible to do it in excel.please make a video.combining jitter plot with box plot in excel.thanks
