How To Determine Sample Size?
I've included a couple of links. Statistical theory can never tell you how many samples you must take, all it can tell you the expected error that your sample should have given the variability of the data. Worked in reverse, you provide an expected error and the variability of the data, and statistical theory can tell you the corresponding sample size. The calculation methodology is given on the related links.
What is the importance of probability and statistics?
The importance of probability and statistics can be found in many business aspects. For example, a loan officer at a bank is going to need to analyze statistical data to determine the feasibility of a loan on a house in a given area. Scientists use probability and statistical data when performing experiments. It is also used in astronomy to calculate where a given star will be at a given time based on past statistical data.
What is a confidence interval?
Answers.com says it is: A statistical range with a specified probability that a given parameter lies within the range. I think that means, just how confident you are that your statistical analysis is correct.
What name is given to a statistical graph where each category has it own wedge and the wedges are displayed on top of one another?
Stack plot.
What is the definition of the golden ratio?
Given two quantities, when the ratio of the larger quantity to the smaller one is equal to the ratio of the sum of the quantities to the larger one, then the ratio is said to be the golden (or divine) ratio. Said another way, given two quantities (a and b), a is to b as a plus b is to a. Expressed symbolically: a : b :: a + b : a Expressed algebraically, it looks like this: a/b = (a + b)/a, where a > b. The golden ratio is approximately 1.6180339887.
What name is given to a statistical graph that plots three or more related quantities simultaneously?
A multivariate graph.
What is the English term given to 7 babies born simultaneously?
Septuplets.

What name is given to a statistical graph that is embellished with additional art work?
Contour map
What is a statistical data?
Statistical data is a list, lists, or charts of facts that are laid out side by side for comparisons sake. Statistical data is all about the numbers and percentages of any given thing. How often? What kind? How popular? Where at? How many? etc.

What's the relationship between fundamental and derived quantities?
According to the (National Institute of Standards and Technology (NIST), "The SI is founded on seven SI base units for seven base quantities assumed to be mutually independent, as given in Table 1.""Other quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations. The SI derived units for these derived quantities are obtained from these equations and the seven SI base units. Examples of such SI derived units are given in Table 2, where it should be noted that the symbol 1 for quantities of dimension 1 such as mass fraction is generally omitted. "Refer to the Related Link below in order to see Table 1 and Table 2.
What is weight factor?
In statistical mechanics ,weight factor is the number of microstates that correspond to a given macrostate
What name is given to a quantity that has both the features of vector and scalar quantities?
Course
What is the relationship between fundamental and derived quantities?
Fundamental quantities are base units that cannot be expressed in terms of other units, while derived quantities are combinations of fundamental units. Most physical measurements involve derived quantities, which are derived from fundamental quantities through mathematical relationships. The relationship between fundamental and derived quantities is essential for establishing a coherent system of measurement.
How can one determine the standard value for a given parameter?
To determine the standard value for a given parameter, one can use statistical methods such as calculating the mean, median, or mode of a set of data points related to that parameter. These values represent typical or average values for the parameter and can help establish a standard reference point.
