3 Building upon or rather correcting a bit on what Babak said.... np.percentile DOES VERY MUCH calculate the values of Q1, median, and Q3. Consider the sorted list below:
running
However, the quartiles are Q1=68.0, Median=85.5, Q3=92.5, which is the correct thing to say What we are missing here is the interpolation parameter of the Thus running

If you want to use raw python rather than numpy or panda, you can use the python stats module to find the median of the upper and lower half of the list:
Line 1: import the statistics module under the alias "stat" Line 2: define the quartile function Line 3: sort the data into ascending order Line 4: get the length of half of the list Line 5: get the median of the lower half of the list Line 6: get the median of the upper half of the list Line 7: print the lower quartile Line 8: print the upper quartile Line 9: print the interquartile range Line 10: run the quartile function for the time_diff column of the DataFrame answered Jun 5, 2020 at 13:38
In my efforts to learn object-oriented programming alongside learning statistics, I made this, maybe you'll find it useful:

I also faced a similar problem when trying to find a package that finds quartiles. That's not to say the others are wrong but to say this is how I personally would have defined quartiles. It is similar to Shikar's results with using mid-point but also works on lists that have an odd length. If the quartile position is between lengths, it will use the average of the neighbouring values. (i.e. position always treated as either the exact position or 0.5 of the position)

If you're interested in using JS, I have developed a solution:
You can just copy paste the codes onto your browser and get the exact result. And more about 'Statistics with JS' can be found in https://gist.github.com/rikyperdana/a7349c790cf5b034a1b77db64415e73c/edit This can be easily done using the python statistics module. https://docs.python.org/3/library/statistics.html
[0.483333, 0.5, 0.516667] The above defaults to 4 groups of data (n=4) with 3 split points (1st quartile, median, 3rd quartile), and setting the method to inclusive uses all the data in the list. The output is a list of 1st quartile, median and 3rd quartile. answered Jul 15 at 5:50
How do you find Q1 and Q3 in Python?running np. percentile(samples, [25, 50, 75]) returns the actual values from the list: Out[1]: array([12., 14., 22.]) However, the quartiles are Q1=10.0, Median=14, Q3=24.5 (you can also use this link to find the quartiles and median online).
How do you find Q1 Q2 Q3 in Python?Calculating Quartiles with Programming. With Python use the NumPy library quantile() method to find the quartiles of the values 13, 21, 21, 40, 42, 48, 55, 72: ... . Use the R quantile() function to find the quantiles of the values 13, 21, 21, 40, 42, 48, 55, 72:. How do you do interquartile range in Python?Use Python to Find the InterQuartile Range of a Dataset. Sort the data.. Calculate Q1 and Q3.. IQR = Q3 — Q1.. Find the lower fence, being Q1 — (1.5*IQR).. Find the upper fence, being Q3 + (1.5*IQR).. |
