The Difference Between

Population and SamplePopulation is the area in which you are trying to get information from. Sample is a section of your population that you are actually going to survey. It is important to have a sample that will represent your entire population in order to minimize biases. For example:

You want in know how American citizens feel about the war in Iraq. Your population: The United States Your sample: 500 citizens selected randomly from each state.

Since the answers all over the US would greatly vary, it is important to have everyone in the population represented in your sample. This is usually done through random sampling, which assumes no biases seeing as the subjects were selected at random.

Populations, parameters, and samples in inferential statistics. Inferential statistics lets you draw conclusions about populations using small samples. Consequently, inferential statistics provide enormous benefits because typically you can not measure and entire

population.

Case study research typically includes multiple data collection techniques and data are collected from multiple sources. Data collection techniques include interviews, observations (direct and participant), questionnaires, and relevant documents, For detailed discussions of questionnaires, interviews and observation,Questionnaires. The most common techniques used to collect data for case studies are:

1.personal interviews

2.direct observation

3.psychometric tests

The key to answering this question is knowing what the mathematical term "period" means.

Period: a period is each group of digits separated by commas in a multidigit number.

Example: 30,149,258 is an 8 digit number so each part of the number separated by a comma is 1 period. {30}{149}{258}

I hope this helped.

Percent Error is the difference between the true value and the estimate divided by the true value and the result is multiplied by 100 to make it a percentage. The percent error obviously can be positive or negative; however, some prefer taking the absolute value of the difference.

The formula is the absolute value of the experimental value (minus) the theoretical value divided by theoretical value times 100.

% error = (|Your Result - Accepted Value| / Accepted Value) x 100

The probability of a head in one flip is 1/2.

The probability of HHHHTT is (1/2)6 = 1/64

The possible correct flips are HHHHTT, HHHTHT, HHTHHT, HTHHHT, THHHHT, HHHTTH, HHTHTH, HTHHTH, THHHTH, HHTTHH, HTHTHH, THHTHH, HTTHHH, THTHHH, TTHHHH, each with a probability of 1/64.

Total probability is 15/64.

Besides anything that is impossible, as noted above, the simultaneous occurrence of two mutually exclusive events has a probability of zero: It is raining and it is not raining, it is on and it is off, etc.

Income is a ratio measure. In ratio measures, one can order categories, specify the difference between two categories, and the value of zero on the variable represents the absence of the variable. Thus, income can take on values of $0, $10, $30,000, etc. Zero dollar income means the absence of income, making income a ratio measurement.

If you're asking for 4 digit numbers where all four digits are odd, then the lowest number possible is 1111, and the highest is 9999. You only have 5 digits to work with. The answer is: 54 - 53 = 625 - 125 = 500.

Subtract the 5 cubed for the numbers less than 1111, which are not four digits.

Since the normal distribution is symmetric, the area between -z and 0 must be the same as the area between 0 and z. Using this fact, you can simplify this problem to finding a z such that the area between 0 and z is .754/2=.377. If you look this value up in a z-table or use the invNorm on a calculator, you will find that the required value of z will be 1.16. Therefore, the area between -1.16 and 1.16 must be approximately .754.
