Is a z test or t test used more often?
t test, because the z test requires knowing the population standard deviation and that's rare. The t test embodies an estimate of the standard deviation.
How do I calculate the standard deviation cube test compressive results of 50486055535157526145?
A single observation, such as 50486055535157526145 cannot have a standard deviation cube test compressive result.
Explain how to find the volume of the rectangular prism shown Then find the volume Each cube is?
This is clearly lifted from some test paper, omitting the vital diagram. The volume of a rectangular prism is the area of the base multiplied by the height. Same for a cube.
What is the significance of standard deviation?
To see how wide spread the results are. If the average (mean) grade for a certain test is 60 percent and the standard deviation is 30, then about half of the students are not studying. But if the mean is 60 and the standard deviation is 5 then the teacher is doing something wrong.
If a test score of 83 was transformed into a standard score of -1.5 and the standard deviation of the scores was 4 what is the mean?
78

How do you get the Quartile Deviation in a grouped data?

How do I calculate the standard deviation cube test compressive results of 50486055535157526145?

Which is better a score of 92 on a test with a mean of 71 and a standard deviation of 15 or a score of 688 on a test with a mean of 493 and a standard deviation of 150?
score of 92
What is a t-test?
a t test is used inplace of a z-test when the population standard deviation is unknown.

This is clearly lifted from some test paper, omitting the vital diagram. The volume of a rectangular prism is the area of the base multiplied by the height. Same for a cube.
When is a t test better than a z score?
When you don't have the population standard deviation, but do have the sample standard deviation. The Z score will be better to do as long as it is possible to do it.
If Tom gets a 70 on a physics test where the mean is 65 and the standard deviation is 5.8 where does he stand in relation to his classmates?
If Larry gets a 70 on a physics test where the mean is 65 and the standard deviation is 5.8, where does he stand in relation to his classmates
When to use t-test?
You use the t-test when the population standard deviation is not known and estimated by the sample standard deviation. (1) To test hypothesis about the population mean (2) To test whether the means of two independent samples are different. (3) To test whether the means of two dependent samples are different. (4) To construct a confidence interval for the population mean.

How are Stanford-Binet intelligence scale results measured?
.The test has a mean, or average, standard score of 100 and a standard deviation of 16 (subtests have a mean of 50 and a standard deviation of 8). The standard deviation indicates how far above or below the norm the subject's score is.
What is another name for the rectangular prism?
I realy dont kown, but everyone say's CUBE........ sorry if you get iterong in a test.* * * * *Sorry to bring bad news but a rectangular prism is a CUBOID. A cube is a square prism.
