• 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
• Introduction..
• 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
• Standard Deviation
• 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
• Correlation
• 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
