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.
It is a value of a test statistic based on the Student's t distribution.
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.
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.
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.

Advantage: * No dishes * Don´t care when it brakes * Can always change themes Disadvantage: * More expensive in the long run * Wasteful * Brakes easily * Ashamed when having people over
Terrible Tiriffic Tad lazy Test

Given T=Z/√(U/ν), Z~N(0,1) and U~χ_ν^2, T follows the Student t-Distribution t_ν Student t-Distribution
Advantage of T beam
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.
no t test is similar to z test because t test ie used for unknown observation and z is for the medicne

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.
