  • 2. A comparative study and data analysis of child sex ratio ofvarious Indian states according to the 1991 census and 2001the census.
  • 3. Child sex ratio is defined as the number of females per thousand males in human populationbetween age group 0-6 years.The term is similar to sex ratio but limited by age group factor. This assignment deals with thestudy of child sex ratios of respective Indian states based on:1. 2001 urban child sex ratio2. 2001 rural child sex ratio3. 2001 total (urban + rural) child sex ratio4. 1991 total (urban + rural) child sex ratioMisuse of advanced prenatal diagnostic techniques has led to sex selection with the widespreadtermination of female foetuses , contributing to a rapidly declining girl to boy child sex ratio.With a higher level of access to such techniques, some of the wealthiest states in India have theworst child sex ratios. Unless urgent action is taken across all sectors to reverse this trend, toeliminate gender discrimination and restore a balanced population, the social repercussions for future generations could be devastating
  • 4. The information was collected from www.unicef.org the official website of theUnited Nations Children’s organization for the respective Indian states for 2001 census ruralareas,2001 census urban areas,2001 census total (rural + urban),1991 census total (rural +urban).Largest & Smallest observations were determined using the max and min function ofMicrosoft Excel, and thus range was calculated for all the four datasets respectively.Class width was calculated using range and number of observations (Class Width = Range /Number of Observations) respectively for each dataset.After the determination of class width and range a continuous frequency distribution wasprepared for each of the datasets respectively along with the less then cumulative frequency ,fx and fx^2.Once the frequency distribution table was made, the histogram was made using the in-builttable function of Microsoft Excel.Other results such as variance, mean, median, mode etc. were calculated by creating userdefined formulas based on the actual statistical formulas.
  • 5. T-ANALYSISAim: To check whether the 1991 total child sex ratio and 2001 total child sex ratio follow which hypothesisamong the following two hypothesis:Null hypothesis:Ho there is no change in the child sex ratio from 1991 to 2001Vs.Alternative hypothesis:Hi there is a change in child sex ratio from 1991 to 2001.Solution:Here di = 2001 total - 1991 total , dbar=∑di/nTable value of t at 5% level of significance and for 34 Degrees of freedom is 2.0336If MOD(tcal) < t34,0.05 we accept Ho otherwise reject Ho.tcal= -5.8237 since MOD(tcal)>t34,0.05 i.e 5.8237 > 2.0336We reject Ho and conclude that child sex ratio has changed in 2001 as compared in 1991A comparison between 2001 total child sex ratio and 1991 total child sex ratio ∑di: -706 ∑di/n -20.6747 ∑(di-dbar)^2 14264.12 S^2 432.246 t -5.82371

  • 12. The avg. of child sex ratio of rural areas is more as compared to urban areasacc. to the 2001 census as per the two comparison charts given above.The child sex ratio has significantly decreased from 1991 to 2001 as per thetwo comparison charts given above.The above data follows alternative hypothesis.The variation of child sex ratio from state to state is more in 1991 ascompared to 2001 census.The variation of child sex ratio from state to state is more in urban areas ascompared to rural areas acc to 2001 census. Steps must be taken in order to balance the falling sex ratio.
