Overview Objective Introduction Tools Used Implementation Conclusion
Objective To find out the most consistent player To find out the better Batsmen/Bowler To conclude that the runs scored are independent of days and weeks
We have analyzed T20 Cricket data of the Indian Team’s performance at the International Level.
Data obtained is of batsmen and bowlers which is distinguished.
ASSUMPTION- Player will not be considered for the consistency test if played only 1 match.
Tools Used Standard Deviation Coefficient of Variance Correlation Chi - square
Is most useful in describing or analyzing a data.
It is also useful for comparative purposes.
It is the minimum when the deviations are measured from the arithmetic mean.
It is the square root of variance
Variance for Ungrouped data 1/n ∑xi^2 – mean^2
Coefficient of Variance
It is also known as Relative dispersion.
It is a stastical measure introduced by Karl Pearson.
It helps in studying the relative dispersion of two or more sets of data.
Lesser the CV, more the consistency.
CV = (S.D/mean) * 100
It is the degree of relationship between two or more variables.
Also referred to as Co-variation.
It is of two types :
1. Simple correlation 2. Multiple correlation In this analysis, we have considered Simple Correlation. ∑xiyi – n.mean(x.y) √(∑xi^2 – nx^-2) * √(∑yi^2 – ny^-2)
Chi - Square
In Chi Square cases, null and alternative hypothesis to be tested are :
H0 : There is no association or dependence of 1 factor on another.
H1 : There is association or dependence of 1 factor on the other.
Uses of Chi Square Test : It is a test of significance for association/ dependence. It is a test of Goodness of Fit. X^2(k-1) = ∑ [(Oi– ei)^2]/ei k i=1
Conclusion Based on the analysis, the names of the players who should be a part of the final T20 Team are : GautamGambhir Yuvraj Singh Rohit Sharma VirendarSehwag M.S.Dhoni R.P.Singh IrfanPathan Harbhajan Singh
