Characterize the types of variables and measures required under a t-Test?
Dependent & independent
WHAT IS THE Difference between A t test and chi square?
t test is used when- a) variables are studied b)the size of sample is a small one.(n<30) chi square test is studied when a) attributes are studied
What statistical test should be used to compare whether one of two variables A or B has the greatest influence on variable set C?
t-test
Why are statistical procedures such as t-tests and analysis if variances not appropriate for use in qualitative studies?
Because a t-test is designed to measure the difference between means on variables that can be measured (interval data). For example, comparing the difference of height between males and females in centimetres. Qualitative studies are not interval data, but qualitative information is coded and analysed by frequencies - you are not comparing two normally distributed variables that can be measured on a continuous spectrum of measurement.
What is significance of x-t graph?
It depends on what the variables x and t represent.
How to test data using SPSS?
You can test data using T-Test in SPSS. Click Analyze > Compare Means > Independent-Samples T-Test to run an Independent Samples T-Test in SPSS. In the Independent-Samples T-Test window, you specify the variables to be analyzed. On the left side of the screen, you will see a list of all variables in your dataset.

Using vector to add objects and display their member variables?
import java.util.Vector; suppose-:::: test t=new test(); /**this is how we add elements to vector*/ Vector v=new Vector(); v.addElements(t);
When an inference procedure is done involving a comparison of two quantitative variables how is the choice between using a two-sample t test or a one-sample matched-pairs test determined?
A matched test is appropriate only if the two variables are measures taken for the same subject.
How you measure a force?
You can measure a force with a force meter or by calculating it by using one of two equations depending on the available variables: ma=F or F=m(v1 + v2)/t
How many phonemes in the word test?
There are four phonemes, or speech sounds, in the word test: t / e / s / t

The second math test was worth half as many points as the first test Write an expression for the total number of points on the 2 test?
t+0.5+t=2t
What is significance of x-t graph?
It depends on what the variables x and t represent.
What are t test and F test In which situation these are applied?
Both are parametric test. The t-test uses a test statistic that is related to the sample mean(s) and is used to compare that with the mean of another sample or some population. The F-test uses a test statistic that is related to the sample variance and is used to compare that with the variance of another sample or some population. Both tests require identical independently distributed random variables. This ensures that the relevant test statistics are approximately normally distributed.
