What are the differences between a two sample t-test and ANOVA hypothesis testing?
In ANOVA, what does F=1 mean? What are the differences between a two sample t-test and ANOVA hypothesis testing? When would you use ANOVA at your place of employment, in your education, or in politics?
How do you combine probability to non probability sampling?
There are many methods: stratified random sampling and cluster sampling are two examples. Suppose you have a school with 1000 pupil: 400 in the Junior school and 600 in the Senior school. You may wish to keep the sampling proportions in the two parts of the school the same. So if you wanted a sample of 5% = 50 pupils, you would take a probability or random sample of 5% = 20 from the Juniors and 5% = 30 from the Seniors. For the second example, imagine you want to sample 5% of all schools in the country. This could result in you spending lots of time and money travelling from place to place. Instead, you divide up the country into 100 regions - each containing the same number of schools. You then take a probability sample of 5% of these regions. In each of the regions you visit every school.
What is the definition of data table?
data cable is an instrument like wire which is used to transfer data or other information from one place to another, one computer to another, the example of this types is LAN,WAN,MAN
If DNA test says 0 probability can it be wrong?
Only if a mistake happened in the lab. This could be due to a mislabeled tube a sample placed in the wrong tube or any number of other misplaced samples or data. Most labs have systems in place to minimise these errors but none are perfect. Humans carry out these tests and humans make mistakes.
When and where are averages used?
averages r used to calculate weight and if u r driving one place to another that is 500km away and took u 5hrs your average will be 100km/hr ;) lol xx
