Statistical methods experimental design and scientific inference

  • What are the experimental methods in statistics?

    Three of the more widely used experimental designs are the completely randomized design, the randomized block design, and the factorial design.
    In a completely randomized experimental design, the treatments are randomly assigned to the experimental units..

  • What are the methods of statistical design?

    Two main statistical methods are used in data analysis: descriptive statistics, which summarizes data using indexes such as mean and median and another is inferential statistics, which draw conclusions from data using statistical tests such as student's t-test..

  • What is the design of experiments and statistical methods?

    The (statistical) design of experiments (DOE) is an efficient procedure for planning experiments so that the data obtained can be analyzed to yield valid and objective conclusions.
    DOE begins with determining the objectives of an experiment and selecting the process factors for the study..

  • What is the relationship between experimental design and statistical analysis?

    Experimental design is the branch of statistics that deals with the design and analysis of experiments.
    The methods of experimental design are widely used in the fields of agriculture, medicine, biology, marketing research, and industrial production.
    In an experimental study, variables of interest are identified..

  • What is the statistical model of the experimental design?

    The (statistical) design of experiments (DOE) is an efficient procedure for planning experiments so that the data obtained can be analyzed to yield valid and objective conclusions.
    DOE begins with determining the objectives of an experiment and selecting the process factors for the study..

  • Why do we use statistical methods to Analyse the results of scientific experiments?

    Statistical methods are tools applied to situations in which we encounter variability, noise and uncertainty.
    They help make more definitive scientific conclusions, and to make better use of available resources..

  • In Statistics, the experimental design or the design of experiment (DOE) is defined as the design of an information-gathering experiment in which a variation is present or not, and it should be performed under the full control of the researcher.
    This term is generally used for controlled experiments.
  • Statistical design of experiments identifies sources of variation, (both random and systematic) and then takes them into account in designing the experiment and in the subsequent analysis.
    Thus the resources expended in carrying out a well designed experiment result in the maximum amount of information.
  • Statistical inference involves hypothesis testing (evaluating some idea about a population using a sample) and estimation (estimating the value or potential range of values of some characteristic of the population based on that of a sample).

How can a researcher design a statistical experiment?

Researchers can design statistical experiments to study several treatments and variables.
For now, we are going to keep the sample case simple so that you can master the basics.
In a statistical experiment, you want to control extraneous variables by holding them constant.

What are inferential statistical procedures in social science research?

Most inferential statistical procedures in social science research are derived from a general family of statistical models called the general linear model (GLM).
A model is an estimated mathematical equation that can be used to represent a set of data, and linear refers to a straight line.

What is a statistical method?

Statistics is the theory and application of mathematics to the scientific method including:

  1. hypothesis generation
  2. experimental design
  3. sampling
  4. data collection
  5. data summarization
  6. estimation
  7. prediction and inference from those results to the population from which the experimental sample was drawn

Probability Theory

Frequentist inference is a type of statistical inference based in frequentist probability, which treats “probability” in equivalent terms to “frequency” and draws conclusions from sample-data by means of emphasizing the frequency or proportion of findings in the data.
Frequentist-inference underlies frequentist statistics, in which the well-established methodologies of statistical hypothesis testing and confidence intervals are founded.

Evidence that either supports or counters a scientific theory

Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis, although scientists also use evidence in other ways, such as when applying theories to practical problems.
Such evidence is expected to be empirical evidence and interpretable in accordance with the scientific method.
Standards for scientific evidence vary according to the field of inquiry, but the strength of scientific evidence is generally based on the results of statistical analysis and the strength of scientific controls.
