Box Plot on Fixed rate
Figure 1 Box Plot on fixed rate
The mean of the fixed rate is 8.49. The median of the fixed rate is 8.34. Similarly the mode of
the fixed rate is 9.99. Since the mean of the fixed rate is higher than the median. Hence the

skewness is positive. The value of the skewness is 0.32. The variance, standard deviation and
range of the fixed rate is 0.90, 0.95 and 3.29.
In the 5th month 1990 the higher variation has been seen.

The empirical rule that is 68-95-99.
At 68%
Mean ± 1* standard deviation
= 8.49± 0.95
= (7.54, 9.44)
At 95%
Mean ± 2* standard deviation
= 8.49± 1.90
