Yes its the best example so far
A biplot is a variety of statistical plot, which is a generalization of the simple two-variable scatter plot, and allows information on both samples and variables of a data matrix to be displayed graphically.
Non-probability or Judgement Samples has to do with a basic researcher assumptions about the nature of the population, the researcher assumes that any sample would be representative to the population,the results of this type of samples can not be generalized to the population(cause it may not be representative as the research assumed) and the results may be biased. Probability or Random samples is a sample that to be drawn from the population such that each element in the population has a chance to be in the selected sample the results of the random samples can be used in Statistical inference purposes
Yes, it is.
The Normal (or Gaussian) distribution is a symmetrical probability function whose shape is determined by two values: the mean and variance (or standard deviation).According to the law of large numbers, if you take repeated independent samples from any distribution, the means of those samples are distributed approximately normally. The greater the size of each sample, or the greater the number of samples, the more closely the results will match the normal distribution. This characteristic makes the Normal distribution central to statistical theory.

The statistical treatment in a thesis is a tool. This tool is used to interpret data in a timely manner.
it explain how we conducted our thesis
A statistical estimate is an estimation of population based on one or many data samples of a group. There are two types of estimates: point and interval.
statistical significance
this part describes the statistical tools used in the research and the reason of the researcher in using such tools.
Treating the cause of an underlying condition is my priority.
yes
To choose the appropriate statistical test, the following four question must be answered; What are your dependent and independent variables? What is scale of measurement of the variables? How many groups/samples are there in the study? Have I have met the assumptions of the statistical test?
It is a part of your thesis where your gathered data is being solved...
Control samples are used as a baseline reference to compare with the experimental samples, which are subjected to a specific treatment or condition. Control samples help to account for variability and ensure that any observed changes in the experimental samples are due to the treatment being tested. Experimental samples are used to investigate the impact of a particular variable or treatment on the system being studied.
The simple answer is you cannot use statistical tests on data collected from quota samples. Unless the sample was collected using a random sampling technique you cannot have any confidence in the results being representative of the population you are sampling. Quota samples are non random. However this does not stop researchers from using statistical tests on quota samples, even if the results can be taken with a pinch of salt!
Independent samples are a set of observations or data points that are not influenced by or related to each other. Each sample is collected without affecting or being affected by the other samples, allowing for statistical analysis to make conclusions about a broader population. This lack of relationship between the samples is important for ensuring the validity of statistical tests and analyses.
