What is a biplot?
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.
What is the difference between convenience judgment and random sampling?
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
Is at the Minnesota zoo do spider monkeys typically weigh more than owl monkeys a statistical question?
Yes, it is.
What is the characteristic of a normal distribution?
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.

Example of a statistical treatment in a thesis?
The statistical treatment in a thesis is a tool. This tool is used to interpret data in a timely manner.
What is statistical treatment?
it explain how we conducted our thesis
What is statistical estimate?
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.
To decide whether observed differences between samples reflect actual differences between?
statistical significance
What is statistical treatment in a research paper?
this part describes the statistical tools used in the research and the reason of the researcher in using such tools.
Example of statistical treatment?
Treating the cause of an underlying condition is my priority.
What are the disadvantages of hiring computer services in the treatment of your statistical data?
yes
How do you choose the most appropriate statistical procedure?
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?
Statistical treatment of data?
It is a part of your thesis where your gathered data is being solved...
What is the difference between control samples and test experimental samples?
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.
What statistical tests can I use on data collected from quota samples?
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!
Definition of independent sample.?
two samples are independent if they are drawn from two different populations, and/ or the samples have no effect on each other. eg: We want to estimate the difference between the mean salaries of all male and all female executives. We draw one sample from the population of male executives and another from the population of female executives. These two samples are independent because they come from different populations and the samples have no effect on each other
