Projection of unforeseen figures is a critical task in various sectors such as the educational sector, finance, or business planning anticipating potential parameters and choosing an appropriate mathematical model is crucial for achieving maximum accuracy. Although no any prediction algorithms can estimate the future perfectly, certain approaches c...

Analysis of data is a very important activity in a quantitative research study. Planning of statistical analysis of research data is as important as designing and conducting a research study. With the proper planning for conducting a study, the identification of accurate statistical procedures, techniques, and statistical tests is also important...

There are different models used for enrolment projection in the education system. Of them ARIMA, double exponential, logistic curve method, reconstructive cohort, and regression model, method are commonly used. Every model has its suitability under certain conditions and with prior assumptions. In India, no attempt was made to estimate enrolment ex...

Policy makers and planners require enrolment data for undertaking an exercise of future planning in respect of educational development. The enrolment projection is an important planning tool to assist in long-range planning and developing action-plans related to resource allocation and system capacity. Various statistical and mathematical models or...

The National Achievement Survey (NAS) is a large scale sample survey conducted to know educational standards across the country through the students. This NAS 2017 was conducted on 13 November 2017 at classes 3, 5 and 8 in all districts in the country. This Technical Report on NAS is based on the data collected from approximately 1,10,000 schools,...

The population of India at 0:00 hour of 1st March 2001, stood 1,027,015,247 comprising 531,277,078 males and 495,738,169 females. As widely believed and expected, India became the second country in the world after China to cross officially one billionth mark. Changes in sex composition largely reflect the underlying socio-economic and cultural patt...

Horticulture can help the farmer's commodity by making farming more remunerative and generating employment. The APEDA has innovated an excellent concept of agriculture export zone adopting a recognizable approach by introducing all steps of farming produce right from production to reach ultimate reasonable market. To ensure better export quality an...

This paper proposes several regression-type chain estimators for estimating the product of two finite population means using two auxiliary variables in double sampling for SRSWOR scheme. Asymptotic properties of the constructed estimators have been studied and their performances are also examined under large sample approximations.

This paper presents the role of statistics in management decision making.

Education especially school education is one of the very important components of social development. Since independence, education has been visualized in government policies as a precursor to national development as well as to better quality of life. Due to the initiative taken by the states and centre, education system in India has expanded expone...

India has a long history of organized education. Gurukuls were traditional Hindu residential schools oflearning; typically the teacher’s house or a monastery. The current system of education, with its western style andcontent, was introduced and funded by the British in the 19th century, following recommendations by Macaulay.Traditional structures...

This paper presents classes of unbiased ratio and product type estimators for finite population mean of study variable using coefficient of variation (CV) of auxiliary variable employing jack-knife technique envisaged by Quenouille (1956). Asymptotic expressions for variance formulae are derived. Numerical illustrations are provided to examine the...

India is the largest producer and consumer of tea in the world, accounts about 29 per cent of world production. In the global trade, Indian production contribution is about 30 per Gent and 23 per cent of China, respectively. This is because of high domestic consumption share of tea in these countries. The production trade in India since 1981 to 200...
