There were 9 people treated using cognitive behavioural therapy (CBT) and 9 people who received no psychological treatment. And we can see from looking at the summary of the mood.gain variable that most people did show a mood gain (mean =.88), though without knowing what the scale is here itβs hard to say much more than that.

How to get summary statistics of a Pandas Dataframe in Python? - Python - Data Science Dojo Discussions
March 24, 2023 - In Pandas, is there a method to get summary statistics for all dataframe columns at once, or should I do it individually for each column? Having an overall data insight through collective statistics before detailed analysis is often beneficial. You can use the following sample dataframe that ...
Top answer 1 of 15

1. tapply
I'll put in my two cents for tapply().
tapply(df$dt, df$group, summary)
You could write a custom function with the specific statistics you want or format the results:
tapply(df$dt, df$group,
function(x) format(summary(x), scientific = TRUE))
$A
Min. 1st Qu. Median Mean 3rd Qu. Max.
"5.900e+01" "5.975e+01" "6.100e+01" "6.100e+01" "6.225e+01" "6.300e+01"
$B
Min. 1st Qu. Median Mean 3rd Qu. Max.
"6.300e+01" "6.425e+01" "6.550e+01" "6.600e+01" "6.675e+01" "7.100e+01"
$C
Min. 1st Qu. Median Mean 3rd Qu. Max.
"6.600e+01" "6.725e+01" "6.800e+01" "6.800e+01" "6.800e+01" "7.100e+01"
$D
Min. 1st Qu. Median Mean 3rd Qu. Max.
"5.600e+01" "5.975e+01" "6.150e+01" "6.100e+01" "6.300e+01" "6.400e+01"
2. data.table
The data.table package offers a lot of helpful and fast tools for these types of operation:
library(data.table)
setDT(df)
> df[, as.list(summary(dt)), by = group]
group Min. 1st Qu. Median Mean 3rd Qu. Max.
1: A 59 59.75 61.0 61 62.25 63
2: B 63 64.25 65.5 66 66.75 71
3: C 66 67.25 68.0 68 68.00 71
4: D 56 59.75 61.5 61 63.00 64

dplyr package could be nice alternative to this problem:
library(dplyr)
df %>%
group_by(group) %>%
summarize(mean = mean(dt),
sum = sum(dt))
To get 1st quadrant and 3rd quadrant
df %>%
group_by(group) %>%
summarize(q1 = quantile(dt, 0.25),
q3 = quantile(dt, 0.75))
