Determine the following types of averages for the discrete dataset in Table 2;

1. Airthmetic Mean
2. Geometric Mean
3. Harmonic Mean
4. Root Mean Square

As the given dataset is large, and the members in it are also large, we use R Software to calculate the mentioned measures.

The R code is given below:

a=c(1716078,465166,148285,94858,89741,84627,38571,26688,16908,14702,12531,30967,148950,83384,69496,55262,33896,26192,23449,15094,11468,16851,405843,272830,239600,232664,181482,163103,148436,58186,46257,41658,37113,32203,30762,24929,23672,23571,19133,17012,16638,11633,11381,10858,182143,44608,25773,84570,34366,17224)

AM=mean(a)
n=length(a)
GM=(prod(a))^(1/n)
HM=1/mean(1/a)
S.D=sd(a)
AM
GM
HM
S.D

Now the output is shown below:

Arithmetic Mean(AM) : 113216.2
Geometric Mean(GM) : 48962.31
Harmonic Mean(HM): 30603.74
Root mean square : 251561.2
