Statistical Services



Statistical services engage the function of statistical techniques to scientific research in health-related fields, including medicine, drug discovery, and clinical trials research. The field of bio-statistics has become an important tool in improving the outcomes in R & D centers. It also commonly involves statistical work in areas of environmental study, agricultural research and biology.
Statistical analyses are used to find hidden information in the data which might not be visible otherwise. The analyses mix the data and try to bring the quintessence of the data by records. Statistical testing and suggestion are used to confirm if a claim or arrangement on the data is valid.

Parametric and Non parametric Test
Statistical tests reduce below two extensive categories- parametric and non parametric. While parametric testing assumes a small amount of conditions on the data, non parametric relaxes these assumptions. There are dissimilar types of tests in these two categories. Only a statistician can conclude which type of test to employ and accurately what test to use for statistical testing.

Segmentation Analysis
Segmentation analysis is typically used in marketing research where the significance lies in defining markets and allocating appropriate resources. It helps divide the whole market into groups and analyzing which group reacts best to their interest. Simply said, it is a technique that spits the market into groups of `like-minded` people who share similar characteristics. The idea is to determine the best groups or segments and a set of characteristics about each of these groups, so you can target them with a finely tuned combine of marketing and sales programs. The deception lies in figuring out what these segments should be.

Perceptual Mapping
Perceptual mapping is a visual map depicting the data based on scales most commonly, two. It is a visual display of potential or obtainable customers that shows the focus of groups of customers with reference to the two scales. It is a visualization of multidimensional scaling practice that helps gain information of the grouping of data. It is a definite data analysis technique where consumer views about a product are plotted on a chart. Respondents’ answers on qualitative attributes like covering, price, presentation and others are mapped on a chart for evaluation. Their team offers perceptual mapping services for market research organizations who want to understand customer state of mind.

Factor Analysis
Factor analysis is a statistical practice that tries to explain the inconsistency caused by variables defined for that study, by variables that underlie the defined ones. It is a data drop off technique designed at dipping the size of the data. The information agreed by, say 100 variables can also be agreed by smaller quantity unnoticed variables. Factor analysis tries to estimate how much of difference in the data is common for all the defined variables and also tries to detect the formation in the connection between variables. It is a data categorization technique. Principal component analysis services are also offered.

Data Analysis and Report Writing
Data analysis prepared using software like SPSS etc aims at getting the quintessence of attention. It helps extract the data into consequential numbers that can project or understand the data more easily. There are different kinds of data analyses and it exclusively depends of the scenery of data and their objective. They offer services ranging from regularity slab and cross-tabs to highly developed analyses like testing, data reduction, mapping, regressions etc. Analysis is meant at extracting what information will be helpful to the client for their objectives.

Report writing is done after data analysis part is concluded and it involves significant and perceptive description of the records got in data analysis. Even though the quantity makes sense for a statistician, it had to be written in configure that considerate is simple for result makers. Reports are proficient with an efficient layout, so it makes intelligence to individual without statistical conditions. Statistical suggestion of records got from analysis is reported in an ordered format with write-ups, tables and charts.
