Statistics is the sociologists of scientific knowledge and practice of developing human knowledge through the use of empirical data expressed in quantitative form. Let our Ph.D. Statistics Assignment Help Experts solve your Statistics homework assignment by providing excellence and clear solution.
STATISTICS
Statistics can be defined as the study measurement and procedures dealing with the collection and organization as well as analysis and interpretation. It is mainly used for the presentation of the data. It can deal with all aspects of data including the planning of data collection in terms of the design of the statistical survey. It can also deal with experimental design.
Statistical methods can summarize as well as describe a collection of data which is known as descriptive statistics. This is useful tool mainly in communicating the results of experiments as well as research. In addition, data patterns may be regarded as a mathematical model which accounts for randomness as well as uncertainty in the observations.

A common goal for a statistical research project is to investigate causality so as to draw a conclusion on the effect of changes in the values of predictors. There are two major types of causal statistical studies that are controlled experiment as well as observational study. In this, both types of studies, the effect of differences of an independent variable or “independent variables” on the behavior of the dependent variable are observed which is the difference between the two types lies in how the study is actually conducted.
The steps of the statistical experiment are as follows:
- Planning the research which includes finding the number of replicates of the study using information such as preliminary estimates regarding the size of treatment effect and the alternative hypothesis as well as experimental error.
- Design of experiments using blocking so as to reduce the influence of confounding variable as well as the randomized assignment of treatments to subjects. This is to allow bias of an estimator of treatments to subject to allow bias of an estimator of treatment effects as well as experimental error. At this stage, statisticians write the protocols which guide the performance of the experiment.
- Performing the experiment following the protocol as well as the analysis of variance.
- The data set is examined in secondary analyses that suggest new hypotheses that have to be studied in the future.
- Documenting as well as presenting the results of the study.

Statisticians improve data quality by developing the specific design of experiments as well as survey sampling. Statistics provides tools for prediction as well as forecasting the use of data and statistical model.
