Explain the role of statistics in research paper

Timely, complete, accurate and reliable statistics is critical for creating and sustaining an environment which fosters strong, equitable development.

For example, if government plans to introduce a universal pension plan, statistical methods will be used to determine the forecasted cost for planned pension scheme with using population projections and inflation data. It is increasingly important to have high quality statistics on the population and projections of the population, for policy development and for planning and providing public services.

Documenting and presenting the results of the study. The difference in point of view between classic probability theory and sampling theory is, roughly, that probability theory starts from the given parameters of a total population to deduce probabilities that pertain to samples.

But what is poverty. Whether or not people notice the importance of statistics, statistics are used by different cohorts of people from a farmer to an academician and a politician in their everyday life.

A set of indicators has been developed to measure progress towards the MDGs and targets and, in turn, the indicators rely on information from robust and reliable national statistical systems. A robust framework for quality assurance is required, particularly for official data. This is another area where statistics plays an important role. See also Chrisman , [48] van den Berg Experimental and observational studies[ edit ] A common goal for a statistical research project is to investigate causality , and in particular to draw a conclusion on the effect of changes in the values of predictors or independent variables on dependent variables. Today, new data collection and monitoring technologies are rapidly becoming available. As highlighted by the Expert Advisory Group on the Data Revolution for Sustainable Development, new data collection and monitoring technologies are becoming rapidly available. Although research in this area is still limited, there is some evidence that more open data and new methods of data collection and use, can save money and create economic, social and environmental value. Hence, statistics are needed to help drive the outcomes that the policies are aiming at. But the mapping of computer science data types to statistical data types depends on which categorization of the latter is being implemented. Also, if data is to be useful and support good decision-making, they have to be ready at the time when decisions are being made or where the opportunity for influencing the outcomes is there. But the value of statistics depends upon their quality. Experiments[ edit ] The basic steps of a statistical experiment are: Planning the research, including finding the number of replicates of the study, using the following information: preliminary estimates regarding the size of treatment effects , alternative hypotheses , and the estimated experimental variability. They must also serve the need of the public to monitor the activities of government and the changes in public well-being.

This kind of model build-up is only possible with availability of timely and reliable statistical information. For instance, statistics holds a central position in fields like industry, commerce, trade, economics, biology, astronomy, etc.

Also, this is an essential ingredient for formulation of sound economic development policies, by which the decision making and development plans of the government becomes concentric. Statisticians recommend that experiments compare at least one new treatment with a standard treatment or control, to allow an unbiased estimate of the difference in treatment effects. Nelder [47] described continuous counts, continuous ratios, count ratios, and categorical modes of data. Each can be very effective. Whether or not people notice the importance of statistics, statistics are used by different cohorts of people from a farmer to an academician and a politician in their everyday life. Every test of significance begins with null hypothesis H0. Many surveys are now being conducted on digital mobile platforms. For instance, preparation of central and provincial government budgets mainly depends upon statistics because it helps in estimating the expected expenditures and revenue from different sources.

Thus, statistics plays a vital role to attain national development goals based on the availability of timely and reliable statistical indices such as GDP, inflation rate, poverty headcount, income per capita, labour force, housing, schooling, health outcomes, etc.

New methods of data collection and analysis based on new technologies may replace or reduce the cost of traditional methods, but they will require additional investments. This trend has effected most young people.

As these potential savings emerge and the quality of statistics improves, priorities for investment in statistics may change. But the mapping of computer science data types to statistical data types depends on which categorization of the latter is being implemented.

Role of statistics in education

Representative sampling assures that inferences and conclusions can safely extend from the sample to the population as a whole. Cyprus can be deemed as an interesting location for a research study as it is a developing country that has adopted and adapted educational ideas, practices and teaching methods from several countries, including the US, the UK and Greece Papanastasiou and Zambylas Finally, improved data sources, sound statistical methods, new technologies and strengthened statistical systems enable better decisions that eventually result in better lives for all of us. This is another area where statistics plays an important role. Statistics is very important when it comes to the conclusion of research. Elementary teachers discussed the economic social ladder and daily statistics about increasing poverty levels. H0 represents the theory that has been put forward, either because it is believed to be true because it is to be used for the basis of argument, but has not been proved Obesity is one of the prominent issues that the society is facing due to the insufficient information that people have regarding the amount of food intake as well as how people ought to balance their diet. The importance and availability of timely and reliable statistics on socio-economic life of a sovereign nation cannot be over-stressed. One of the most important applications of this map was to inform policy makers during the reform of the Samurdhi transfer programme in , when the Ministry of Samurdhi used the map to identify the poorest DS divisions in the country. It also improves accuracy, simplifies collection of GIS and image data, streamlines integration with other information streams, and opens up the possibility of incorporating micro-chip based sensors into survey processes.

Statistical systems are empowered, resourced and independent today, to quickly adapt to the new world of data to collect, process, disseminate and use high-quality, open, disaggregated and geo-coded data, both quantitative and qualitative.
