Why are random samples more representative of the population than other kinds of samples?
A 'random' sample - covers all age groups, genders, and other criteria. A 'targeted' sample might only cover a small part of the population.
Difference between sample regression and population regression line?
AnswerA sample is a subset of a population. Usually it is impossible to test an entire population so tests are done on a sample of that population. These samples can be selected so that they are representative of the population in which cases the sample will have weights, strata, and clusters. But usually people use random samples. So it's not that the line is different, it's that the line comes from different data. In stats we have formulas that allow a sample to represent a population, if you have the entire population (again unlikely), you wouldn't need to use this sample formulas, only the population formulas.
How to reduce sampling error?
The only way to get rid of sampling error is to use the entire population under study. This is usually impossible, so the next best thing is to use large samples and good sampling methods.

What are cardiac ct angio result samples?
The cardic CT angio result samples refer to the samples that are usually taken to diagnose the heart problems.
Marketing researchers usually draw conclusions about large groups of consumers by studying which small components of the total consumer population?
Marketing researchers study small components of the total consumer population, known as samples, to draw conclusions about the larger group. These samples are representative of the larger population and allow researchers to make inferences about consumers as a whole based on their findings. By studying these samples and analyzing the data collected, researchers can gain insights into consumer behavior, preferences, and trends.
The fundamental attribution error says that when you explain the failures and shortcomings of others you usually underestimate the significance of?
situational factors.
What does the medical term preserved mean?
The term preserved usually refers to samples, such as those taken for analysis. Preservation keeps the samples, usually some kind of body tissue, from spoiling or degenerating.

How do you take a blood sample from a nerve?
You don't. Blood samples are usually taken from a blood vessel.
Why are liability insurance quotes varied from one company to the next?
