Why need the statistics in medical sciences?
Statistical analysis is important in many branches of science. When understood and correctly applied, statistics can help us decide whether or not the results of a research project support the initial claim of the researchers.
How does sample size affect validity of results in a research?
A large sample reduces the variability of the estimate. The extent to which variability is reduced depends on the quality of the sample, what variable is being estimated and the underlying distribution for that variable.
Why is a voluntary response sample not suitable for a statistical study?
Voluntary response sample is not generally suitable for statistical study because its results are not likely to be the representative of the entire population under study.Such results could be biased as those who made effort to respond voluntary have strong feelings or opinions whether favorable or unfavorable regarding the subject of consideration.
Do data analysis help people in understanding the result of a survey conducted?
Data analysis must be used to understand the results of a survey. Otherwise, the data collected by the survey would remain a jumbled collection of data.
What is the difference between Microsoft SSAS and SPSS?
Microsoft SSAS (SQL Server Analysis Services) and SPSS(Statistical Package for the social sciences) are two different software tools designed for different purposes. Let's discuss the differences between them. Microsoft SSAS is an analytical data engine provided by Microsoft as part of the SQL Server suite. It is used for creating and managing online analytical processing (OLAP). SSAS enables multidimensional and tabular data analysis and provides features for data modelling, data aggregation, and advanced calculations. It is typically used for business intelligence and data warehousing applications, allowing users to analyze large volumes of data and gain insights for decision-making. SPSS is a software package primarily used for statistical analysis and data management in social science research. It provides a comprehensive set of tools and techniques for data exploration, descriptive statistics, hypothesis testing, regression analysis, and more. SPSS offers a user-friendly interface that allows researchers to import data, perform statistical analyses, and generate reports or visualisations of the results. In summary, the main difference between Microsoft SSAS and SPSS is their primary purpose and functionality. SSAS is focused on creating OLAP cubes and data mining models for business intelligence and data warehousing, while SPSS is dedicated to statistical analysis and data management in social science research.
The variability of a solution to changes in the model and input data is an important part of the analysis of the results?
sensitivity analysis
How do I interpret the results of regression analysis?
Interpreting the results of regression analysis involves assessing the statistical significance, coefficients, and goodness-of-fit of the model. Here are some key steps to help you interpret regression results: Statistical Significance Coefficients Magnitude of Coefficients Adjusted R-squared Residuals Assumptions Remember, interpreting regression analysis results should consider the specific context of your study and the research question at hand. It is often helpful to consult with a statistician or your research supervisor to ensure a comprehensive understanding and accurate interpretation of the results.
What does data mean in science?
Data are either the results of experiment express in the measure form of numbers, or those numbers under some conditions of statistical analysis.
What is data analysis in a science fair project?
A data analysis is when you interpret and analyze your results. If you made graphs, include and explain them here. Your answer should include the questions.
What has the author B D Hall written?
B. D. Hall has written: 'Analysis of the results of a survey of shoppers in south Hampshire' 'Organisation, response, tabulations and statistical analysis of the South Hampshire housecondition survey 1970'
Why do you sometimes repeat readings three times in science?
Performing a measurement or an experiment three-times is called a triplicate. Triplicate results make statistical analysis better and prevent the possibility of unusual results due to natural/artificial variation.
How do you calculate measurement uncertainty for protein?
Same way as for anything else: run multiple samples and do a statistical analysis on the results, just like you (should have) learned in analytical chemistry class.
What has the author Henry S Dyer written?

Dyer has written: 'How to achieve accountability in the public schools' -- subject(s): Educational accountability 'Manual for analyzing results of an educational experiment (analysis of covariance)' -- subject(s): Analysis of covariance, Examinations, Factor analysis, Interpretation, Statistical methods
Why synapsis is the key to the diversity that results from meiosis?
The purpose of synapsis is to increase genetic variability
Why pseudoscience is the polygraph?
Some consider the polygraph a pseudoscience because of the variability of the results of polygraphic testing.
Is Robinson a Jewish name?
I know people named 'Robinson who are Jewish. I also know people named 'Robinson' who are not Jewish. According to statistical analysis of the results of my rigorously unscientific survey, the answer is: Definitely not necessarily, but it could be.
What are application of Microsoft Excel as statistical tool?
Microsoft Excel is mainly for numerical analysis and manipulation. It has a wide range of statistical functions, about 80 specifically classified as being for statistics as well as many standard functions which can be used for statistics. So many areas of statistical analysis, like doing surveys, evaluating census results, comparing laboratory experiment results, looking for trends in figures, probability, etc. can all be done with Microsoft Excel. It can also be used to present figures in a structured format. Microsoft Excel also provides a wide range of charts, some of which are particularly good for dealing with statistics.
