1. How to deal with questions as shown below? according to the data I gave, if there is any data you want, you can ask me. (the assignment in question means A1 and A2)

ii. Which summary statistics are the most appropriate to summarize the location and spread of the two distributions ? why? [3 marks] iii. Compare the distribution of the marks for each assignment using the summary statistics you have selected for location and spread? [2 marks] a Al A2 mean 38.560 33.640 standard deviation 5.563 5.522 median 39.500 34.500 IQR 8.000 6.500 (b) Histogram of Maths_Marks$A1 20 40 60 80 100 Frequency O 15 20 25 30 35 40 45 50 Maths_Marks$A1 Figure 1: the histogram graph of group Al.Histogram of Maths_Marks$A2 c: D 1 C: an >-.
