The Student's t-test is advantageous because it is simple to use, requires minimal assumptions about the data, and is effective for comparing means between two groups, especially with small sample sizes. However, its main disadvantage is that it assumes the data are normally distributed; violations of this assumption can lead to inaccurate results. Additionally, the t-test is limited to comparing only two groups at a time, which can be a drawback when analyzing multiple groups simultaneously.

What is a t value?
It is a value of a test statistic based on the Student's t distribution.
What advantage does the one-sample t offer over the z-test?
The one-sample t-test offers an advantage over the z-test when sample sizes are small (typically n < 30) and when the population standard deviation is unknown. While the z-test requires knowledge of the population standard deviation, the t-test estimates the standard deviation from the sample, making it more appropriate for smaller samples. Additionally, the t-distribution is more spread out and accounts for increased variability in smaller samples, providing more accurate confidence intervals and significance tests.
What is the t test used for?
The"t" test, (called the "small 't' test, to distinguish it from the large 'T' test) is a test for deviation from a known norm, using a smaller sample set than the one required by the large T test. It is said to have been developed by the head of quality control at the Guinness Brewery in Ireland.
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.
Is t-test a parametric test or not?
yes

Is the sewers a safe place for a CT in cs siege?
Depends-> If you are easily defeated by T Forces Or if you're playing Easy Mode and you are very capable of killing a certain amount of T Forces, it may be advantage for you. However, it can also disadvantage you if your skills aren't so good.
Is T test similar to Z test?
no t test is similar to z test because t test ie used for unknown observation and z is for the medicne

What does the student's t-distribution refer to in statistics?
The Student's T- Distribution is a type of probability distribution that is theoretical and resembles a normal distribution. The Student T- Distribution differs from the normal distribution by its degrees of freedom.
