Statistics


Hypothesis: MPs above a certain age have a low attendance.


MPs below 50 MPs above 50
Mean 74.09 79.07
Standard Deviation 17.34 16.23
N 161 333

t = 3.0556
p = 0.0024

Since the p-value of the sample is 0.0024 we can say with 0.24 % confidence that the difference in the samples is due to random sampling. Hence we can reject the hypothesis that the two samples are of the same population. Hence comparing the mean the Attendance of old MP's is better than young MP's.

Hypothesis: MPs from small states maintain better attendance in parliament.


MPs from large states MPs from small states
Mean 76.82 81.3
Standard Deviation 16.47 14.48
N 290 44

t = 1.8730
p = 0.0659

Since the p-value of the sample is 0.0659 we can say with 6.59 % confidence that the difference in the samples is due to random sampling. Hence we can't reject the hypothesis that the two samples are of the same population because maximum value of p  is 0.05 for rejection.


Hypothesis: MPs from UPA (in power) or NDA (opposition) maintain better attendance.


MPs from UPA/NDA Other MPs
Mean 78.09 75.84
Standard Deviation 16.63 16.98
N 141 490

t = 1.3383
p = 0.1820

Since the p-value of the sample is 0.182 we can say with 18.2 % confidence that the difference in the samples is due to random sampling. Hence we can't reject the hypothesis that the two samples are of the same population because maximum value of p  is 0.05 for rejection.


Hypothesis: MPs from North India maintain a better attendance than MPs from South India.


MPs from North India MPs from South India
Mean 80.53 73.21
Standard Deviation 14.98 17
N 134 117

t = 3.5997
p = 0.0004

Since the p-value of the sample is 0.0004 we can say with 0.04 % confidence that the difference in the samples is due to random sampling. Hence we can reject the hypothesis that the two samples are of the same population. Hence comparing the mean the Attendance of north India is better than South India.

Hypothesis: More educated MPs maintain better attendance.


Less Educated MPs Highly Educated MPs
Mean 74.82 78.27
Standard Deviation 18.48 16.13
N 112 381

t = 1.7869
p = 0.0758

Since the p-value of the sample is 0.0758 we can say with 7.58 % confidence that the difference in the samples is due to random sampling. Hence we can't reject the hypothesis that the two samples are of the same population because maximum value of p  is 0.05 for rejection.

Hypothesis: Female MPs are better educated than male MPs.


Female MPs Male MPs
Mean 62.5 60.81
Standard Deviation 20.3 20.09
N 60 490

t = 0.6106
p = 0.5433

Since the p-value of the sample is 0.5433 we can say with 54.33 % confidence that the difference in the samples is due to random sampling. Hence we can't reject the hypothesis that the two samples are of the same population because maximum value of p  is 0.05 for rejection.
