All of the questions must be answered by R language.

givenarray <- c(34,87,56,97,23,65,76,35,21,79,88,99,54)

1.

Try to create a function which calculates the mod of a given array

to find mod without built-in function(mod())

use unique(), tabulate() functions

2.

Calculate the standard deviation of given array

without using sd() function.

use sqrt() function

3. Create a barplot with given array and label the x axis with the letters given below

x, y, z, a, b, c, d, p, o, c, e, m, n

4. outliers can be found by (min - (1.5*IQR)) or (max + (1.5*IQR)) Now add two outlier values to given array and re-draw the boxplot
