What is a t value?
It is a value of a test statistic based on the Student's t distribution.
What does the test statistic measure?
The test statistic is a measure of how close the sample proportion is to the null value.
What sample statistic is used to estimate a population parameter?
A point estimate is a single value (statistic) used to estimate a population value (parameter)true apex
What is the calculated numerical value that is compared to a table value in a hypothesis test called?
It is the test statistic.
Which value in an anova table is of greatest interest?
Usually the F-statistic.
How do you find p value with test statistic and critical value?
Normally you would find the critical value when given the p value and the test statistic.
What is a t value?
It is a value of a test statistic based on the Student's t distribution.
What does the test statistic measure?
The test statistic is a measure of how close the sample proportion is to the null value.
What sample statistic is used to estimate a population parameter?
A point estimate is a single value (statistic) used to estimate a population value (parameter)true apex
What is the p value of a test statistic of 1.369?
The answer depends on what the test statistic is: a t-statistic, z-score, chi square of something else.
What statistic is always based on two values?
The range. Highest value minus lowest value.
What is the calculated numerical value that is compared to a table value in a hypothesis test called?
It is the test statistic.
What statistic is always based on just two values?
The range. Highest value minus lowest value.
What is a single value representing a group of numbers?
It could be a summary statistic - although there are several different options available.
Which value in an anova table is of greatest interest?
Usually the F-statistic.
Explain how to standardize a value in statistics?
The term effect size can refer to the value of a statistic calculated from a sample of data.
As the sample size increases what does the expected value of M do?
You have not defined M, but I will consider it is a statistic of the sample. For an random sample, the expected value of a statistic, will be a closer approximation to the parameter value of the population as the sample size increases. In more mathematical language, the measures of dispersion (standard deviation or variance) from the calculated statistic are expected to decrease as the sample size increases.
