Test cricket is the longest version of the sport of cricket.
 Test matches are played between international teams of eleven players each over four innings; each team bats twice.
 In the women's variant, the game is scheduled to last four days of play.
 The Women's Cricket Association was formed in England in 1926, and the first women's Test was played between England and Australia in 1934.
 The English team were on a tour of Australia and New Zealand, arranged by the WCA.
 The International Women's Cricket Council was formed in 1958 as the governing body for women's cricket.
 In 2005, women's cricket was brought under the International Cricket Council along with men's cricket; at that time 89 of the council's 104 members had started developing women's cricket.
 As of January 2016, a total of ten teams have played a total of 138 women's Test matches and 2 matches were abandoned.
 England have played the most matches (93) while Sri Lanka, Ireland and the Netherlands have played only one Test each.
Test matches (matches of Test cricket) in the 19th century were somewhat different affairs than what they are today.
 Many of them were not designated as Test matches for many years afterwards, and it is possible that some Test players never knew they had played in a Test.
 Before 1888 there had been 26 Test matches, all between England and Australia.
 England had won 13 of them, Australia 9, with 4 draws.
 During the 19th century England played in all the Tests, which were mostly against Australia, though a few were against what tended to be a very weak South African XI.
Edwin Lloyd St Hill (9 March 1904 – 21 May 1957) was a Trinidadian cricketer who played two Test matches for the West Indies in 1930.
 His brothers, Wilton and Cyl, also played for Trinidad; in addition, the former played Test matches for the West Indies.
 St Hill first played local cricket in Trinidad with some success and graduated to the Trinidad team.
 He played regularly for the next five years but was not selected for any representative West Indian teams.
 His increased success in 1929 attracted the attention of the West Indies selectors, and he played two Test matches against England in 1930.
 Although not particularly successful, he bowled steadily and was chosen to tour Australia with the West Indies in 1930–31.
 He was fairly effective in first-class games but the form of the other fast bowlers in the team meant that he was not chosen for any of the Test matches.
The Indian cricket team toured Sri Lanka from 6 August to 1 September 2015 to play a tour match and three Test matches.
 On 27 June, Sri Lankan batsman Kumar Sangakkara said he would retire from international cricket after the second Test of the series.
 The Board of Control for Cricket in India (BCCI) and Sri Lanka Cricket Board confirmed the schedule of India's tour to Sri Lanka in August to September 2015.
 The tour started with a three-day warm-up game against Sri Lanka Board President's XI, followed by three Test matches.
 The Test matches were played at Galle, P Sara Oval, and SSC Colombo.
 The Indian team arrived in Sri Lanka on 4 August 2015.
Arjan Kripal Singh (born 13 February 1969 in Madras (now Chennai), Tamil Nadu), is an Indian cricketer.
 He is a right-handed batsman and a right-arm medium-pace bowler.
 He hails from a family of cricketers with his grandfather A. G. Ram Singh playing in two unofficial Test matches, his father A. G. Kripal Singh (14 Test matches) and uncle A. G. Milkha Singh (4 Test matches) representing India in Test cricket.
 Another uncle A.G. Satwender Singh played first class cricket for Madras cricket team and Tamil Nadu cricket team.
 His brother Swaran Kripal Singh played in domestic cricket briefly.
 His grandfather hailed from Amritsar, Punjab (India) who settled down in Madras and played for the local team.
 All members of the family played for the local team only.
A "Z"-test is any statistical test for which the distribution of the test statistic under the null hypothesis can be approximated by a normal distribution.
 Because of the central limit theorem, many test statistics are approximately normally distributed for large samples.
 For each significance level, the "Z"-test has a single critical value (for example, 1.96 for 5% two tailed) which makes it more convenient than the Student's "t"-test which has separate critical values for each sample size.
 Therefore, many statistical tests can be conveniently performed as approximate "Z"-tests if the sample size is large or the population variance is known.
 If the population variance is unknown (and therefore has to be estimated from the sample itself) and the sample size is not large (n < 30), the Student's "t"-test may be more appropriate.
The 2016–2017 international cricket season was from September 2016 to April 2017.
 During this period, 41 Test matches, 87 One Day Internationals (ODIs), 43 Twenty20 Internationals (T20Is), 4 first class matches, 16 List A matches, 41 Women's One Day Internationals (WODIs), and 15 Women's Twenty20 Internationals (WT20Is) were played.
 Of the 41 Test matches that took place in this season, 3 were day/night Test matches.
 The season started with Pakistan leading the Test cricket rankings, Australia leading the ODI rankings, New Zealand leading the Twenty20 rankings, and Australia women leading the Women's rankings.
Robert Neil Harvey MBE (born 8 October 1928) is a former Australian cricketer who represented the Australian cricket team between 1948 and 1963, playing in 79 Test matches.
 He was the vice-captain of the team from 1957 until his retirement.
 An attacking left-handed batsman, sharp fielder and occasional off-spin bowler, Harvey was the senior batsman in the Australian team for much of the 1950s and was regarded by Wisden as the finest fielder of his era.
 Upon his retirement, Harvey was the second-most prolific Test run-scorer and century-maker for Australia.
Raymond Harvey (born 3 January 1926) is a former Australian first-class cricketer who played for Victoria in the 1940s and 1950s.
 He was the brother of Australian Test batsmen Merv and Neil and first-class cricketer and umpire Mick Harvey.
 Ray Harvey was an attacking and talented batsman but failed to reach international standards and only managed to hold down a regular position in the Victorian team in two seasons in the 1950s.
 This failure to match the standards set by his Test-capped brothers was often attributed to a lack of single-mindedness and hunger.
The Indian cricket team toured Australia from 24 November 2014 to 10 January 2015.
 The tour consisted of two tour matches and four Test matches.
 The first Test was originally scheduled on 4 December in Brisbane, but it was postponed because of the death of Phillip Hughes.
 Instead, Adelaide hosted the first Test from 9 December and the Brisbane hosted the second Test from 17 December.
 Following the draw in the third Test, Indian captain MS Dhoni announced his retirement from Test cricket with immediate effect.
 After the draw in the final Test in Sydney, Australia won the series 2–0.
 Following the Test matches, Australia and India participated in the Carlton Mid Triangular Series with the England cricket team.
