Trident University Data analysis is a procedure of inspecting, cleaning, transforming, and modelling data with the goal of highlighting useful information, suggesting conclusions, and supporting decision making. There are multiple facts and approaches, encompassing diverse techniques under a variety of names, in different business, science, and social science domains in data analysis. For data analysis we have to mine the data first for our purpose such that the data we can handle easily. Basically for data analysis our first thing to do our planning, how we are going to collect the data, our going data going to make sense or not, actually data will be meaningful for our object, after …show more content…
Populations defined by race, age, sex or income can often be directly estimated using census data. When population characteristics cannot be measured using Census data, topical sample surveys are the next best source of data. After that question may arise for this survey which children we take for our survey and which age of children we are going to consider. Children with special health care needs (CSHCN) include children with a wide variety of health conditions. Some of these children also have more than one condition. Estimation of the number of CSHCN may involve identifying. The prevalence of children with special needs as identified by state and federal programs, The prevalence of specific diseases and conditions in children, the prevalence of functional limitations among children, the proportion of children who require or need specialized services, and the proportion of children who are regarded by others as disabled. Because there is no data source from which a direct measurement of the size of this population can be estimated and because of the diversity of definitions, no one method alone will completely provide an all-inclusive estimate of the prevalence of CSHCN. Therefore, averaging and/or summing multiple types of estimates may be required. Before we can create an estimate it is important to understand the variety of ways that this population may be defined. Sampling frame: In a perfect survey, the target
Data taken from the 1997-2008 National Health Interview Surveys of US showed that 1 out of every 6 children had developmental disabilities (Boyle et al, 2011). These disabilities were tabulated as including autism, attention deficit hyperactivity disorder, and other forms of developmental delay. According to the survey, these disabilities increased and now require more health and education interventions. Children aged 3-17 years old participated in the survey. Parent-respondents reported their children's diagnoses as including attention deficit hyperactivity disorder, intellectual disability, cerebral palsy, autism, seizures, stuttering or stammering, hearing loss, blindness, learning disorders and other forms of developmental delay. These disabilities were much more prevalent in boys than in girls. They were lowest among Hispanic children as compared with non-Hispanic white and black children. Low income and public health insurance were associated with the prevalence. The rate of these disabilities increased from 12.84% to 15.94% in the last 13 years. Autism, ADHD and other developmental delays increased in all socio-demographic sub-groups, except for autism among non-Hispanic black children. The survey called for additional research on the influence of changing risk factors and changes in the acceptance and the benefits of early services (Boyle et al).
The prevalence of children with disability is ranged from 0.4% to 12.7 %, where 85% of them are living in developing countries. It is estimated that the number of children who live with a moderate to severe disability is 93 million (UNICEF, 2013). The wide range of estimated prevalence across countries is due to selection of different measurement methods and definitions of disability. Especially in developing countries,
With increasing data the storage of the data must also be increased, which is a problem. So, data is stored or recorded in the form of computer data bases which makes easy to access the right data at any given point of time. To extract the right data from all these present volumes of data, usually certain traditional way of data analysis like regression analysis, cluster analysis, numerical taxonomy, multi-dimensional analysis, time series analysis , estimation outcome analysis and many more are used.
Data mining is the procedure of getting new patterns from large amount of data. Data mining is a procedure of finding of beneficial information and patterns from huge data. It is also called as knowledge discovery method, knowledge mining from data, knowledge extraction or data/ pattern analysis. The main goal from data mining is to get patterns that were already unknown. The useful of these patterns are found they can be used to make certain decisions for development of their businesses. Data mining aims to discover implicit, already unknown, and potentially useful information that is embedded in data.
Data mining is the process through which previously unknown patterns in data were discovered. Another definition would be “a process that uses statistical, mathematical, artificial intelligence, and machine learning techniques to extract and identify useful information and subsequent knowledge from large databases.” This includes most types of automated data analysis. A third definition: Data mining is the process of finding mathematical patterns from (usually) large sets of data; these can be rules, affinities, correlations, trends, or prediction models.
Data is one of the important factors in data forecasting studies because data represents the whole source of the business purpose of the study.
Data mining (sometimes called data or knowledge discovery) is the process of analyzing data from different perspectives and summarizing it into useful information - information that can be used to gain competitive advantage, improve processes, gain efficiency, save costs, utilizing and allocating resources optimally.
Data Analysis is a process of spreading the data on simplest way so that it can assist in interpretation. Some of the prominent data analysis methods are: statistical support, cluster analysis, multidimensional scaling, and factor analysis. Data analysis can be used to transform data or to summarize the data itself or its statistical report.
Data mining is a set of automated techniques used for extracting hidden information and discovering useful patterns exist in the data sets.
Data mining is finding the routines and examples in large databases to guide choices about future exercises. It is normal that data mining tools to get the model with negligible information from the client to identify. Data mining is the utilization of automated data analysis techniques to discover already undetected connections among data things. It regularly determines the

The researcher will use largely qualitative data analysis which according to Glaser (1992) is any analysis that produces findings or concepts as in grounded theory that are not arrived at by
Abstract— Data mining is a logical process that is used to search through large amount of data in order to find useful data [2].There are many different types of analysis that can be done in order to retrieve information from big data. Each type of analysis will have a different impact or result. Which type of data mining technique you should use really depends on the type of business problem that you are trying to solve.
After collecting the data we enter into the process of data selection. It is not enough if we simply collect the data, it is also necessary to select the data that we going to process. There are many data
Data Mining is known as the process of analyzing data to extract interesting patterns and knowledge. Data
