Hi Aiysha,
Well, try!!!
Box plot will be drawn only on scoress06.PNG

For example, if you expand the data on scores then the following show above will occur meaning:
the player had scored 3 points in two games, 6 points in one game, 7 points in 2 games, etc. and if you expand it you will get the following.

So, for that data only you need to calculate quartiles (Q1, Q2, Q3, mean, median, variance, standard deviation) and draw the box plot.

Note: Don't consider outliers to make decisions. (Eg: the player had scored 30 points in one game. But 30 is an outlier. We should not consider by making decision-based on outlier)

Hope I am clear to you. Submit again by considering the points mentioned above.

Excellent and really appreciate the work you did. Keep doing !!

Thanks,
Srikanth

Hi Srikanth,

i have a doubt.
i am trying to calculate IQR for even number of samples.
7 8 9 9 10 10 11 11 12 13, Q2=10(5th, 6th position)
for calculation of Q1, from where should i consider--> from 1st : 5th or 1st : 6th position?
 
Hi Srikanth,

Please find attached my attempt of the Day 2 assignment. Please let me know if my findings are correct. Also, request you to please check if the individual values(Q1, Q2, Q3, IQR, Standard Deviation) have been calculated correctly. In the materials, the variance and S.D. formula have the denominator as 'n-1', but I have used 'n' as you had explained. Please let me know which one is correct.

Thanks and Regards,
Amrita

Hi Srikanth ,
I have expanded the scores based on the frequency.
Player 2 has the lowest std dev of 3.4 hence player 2 is the best i suppose
Pls check the box plots and advise
Could you kindly confirm your linkedin profile

Good job, however few suggestions,
6) As I am asking for 2nd element so the index is 1, hence the answer is print(type(my_tup[1]))
7) my_tup[::-1]
