Introduction –
A cricket bat is a specialized piece of equipment used by batsmen in the sport of cricket to hit the ball, typically consisting of a cane handle attached to a flat-fronted willow-wood blade. It may also be used by a batsman who is making his ground to avoid a run out, if he holds the bat and touches the ground with it. The length of the bat may be no more than 38 inches (965 mm) and the width no more than 4.25 inches (108 mm). Its use is first mentioned in 1624. Since 1979, a law change stipulated that bats can only be made from wood.
View / Review –
The blade of a cricket bat is a wooden block that is generally flat on the striking face and with a ridge on the reverse (back) which concentrates wood in the middle where the ball is generally hit. The bat is traditionally made from willow wood, specifically from a variety of white willow called cricket bat willow (Salix alba var. caerulea), treated with raw (unboiled) linseed oil, which has a protective function. This variety of willow is used as it is very tough and shock-resistant, not being significantly dented nor splintering on the impact of a cricket ball at high speed, while also being light in weight. The face of the bat is often covered with a protective film by the user.
Modern bats are usually hand made in the Sub-continent (Pakistan or India) due to the low cost of labour. However a few specialists in England, Australia, and New Zealand still make bats, mostly with use of a CNC lathe.
Traditional Indian cricket bats are made in the regions of Jammu and Kashmir, Punjab, Haryana, Gujarat, Uttar Pradesh and Rajasthan.[citation needed] In Kashmir they are made out of willow found in northern India. Some bats made in Kashmir are of international standards and are/were used by national players in India Sunil Gavaskar, Virender Sehwag and Yuvraj Singh.
Data Collection –
For testing the usage of the cricket bat a survey was conducted where 30 cricketers were asked to fill a simple survey questionnaire where they were asked to rate their favorite brand of cricket bat.
Data Analysis –
Hypothesis:
H0: All types of athletic footwear brands are same
H1: Any one of them is Different
F= 0.05 6 DF 172DF = 3.1
Conclusion:
As calculated F is more than tabulated F, Reject H0 & Accept H1, which means any one of them, is different.
