Given data:

Time spent studying for the Homework. 6 11 8 7 4 14 1 10 5 12

a)

box plot for above data:

b)

discriptive analysis for above data:

Discriptive Value
Mean 7.8
Median 7.5
Standard Deviation 4.0
Sample Variance 16.0
Skewness -0.1
Range 13
Minimum 1
Maximum 14
Sum 78
Count 10

for discribing the distribution is diffcult with this data. because the point frequency is one. so if we have to discribe the distribution we need more data point.

histogram for above data given below.

so for discribing we need more data,
