Creation of an unnaturally uniform sample to represent a diverse population can be avoided by what?
Selecting individuals at random- *apex
Why do we sample and estimate populations?
The bottom line is it would be wasteful and foolish to use the entire population when a sample, drawn scientifically, provides accuracy in representing your population of interest. Assessing all individuals may be impossible, impractical, expensive or even inaccurate.
What are some examples where the mean the median and the mode might be the same?
(10, 15, 15, 15, 20) The answer above displays a sample in which the sample mean, sample median and sample mode assume the same value. If you were asking about populations, then the population mean, population median and population mode are the same whenever the probability density function for the population is symmetric. For example, the normal probability density function is symmetric, the t and uniform density functions are symmetric. Many are.
What sentence is a true statement Is a sample a subset of the population or Is a population a subset of the sample?
A sample is a subset of the population.
How is a sample different from a population?
The sample is a subset of the population.
When using data from population genetics research the sample must be?
The sample must have a high probability of representing the population.
Does the accuracy of a sample in representing the characteristics of the population from which it was drawn always increase with the size of the sample?
yes the size is 4444
What is the set of numbers representing some sort of information from the sample or population?
Observations.
What are the set of numbers representing some sort of information from the sample or population?
The general term statistics might be the set of numbers representing some sort of information from a sample population. The term data set can also be applied.
What is a set of numbers representing some sort of information from the sample or population?
Statistics or data set

Sketch a relative frequency histogram for the 36 sample means Use nine classes In this histogram approximately bell shaped and symmetric?
you have to find the class size by: (max-min)/number of classes Then use that class size to setup the class ranges Then use the class ranges to determine the frequency a sample occurs in each class. make a chart using the class ranges and the sample frequencies to display the histogram
What are a set of numbers representing some sort of information from the sample population?
One example is the "Five Number Summary" consisting of the sample's minimum, lower quartile, median, upper quartile and maximum.
Why do we sample and estimate populations?
The bottom line is it would be wasteful and foolish to use the entire population when a sample, drawn scientifically, provides accuracy in representing your population of interest. Assessing all individuals may be impossible, impractical, expensive or even inaccurate.
