What is Z-Test?

A Z-test is used in statistics to decide whether the means of two population are different when sample sizes are large and when you know the variances. This test has a normal distribution and you should know the standard deviation to perform an accurate z-test.

Z-tests are related to t-tests closely, however, when the sample sizes are small, t-tests are performed. In z-tests, the standard deviation is known but it is unknown in t-tests. Z-test is a hypothesis test wherein it has a normal distribution. This test is used for samples that are greater than 30. When you conduct a z-test, you should state z-score, alternative and null hypotheses. You can contact us and send us your requirements.

Assumptions in a Z-Test

The assumptions are highlighted when you  Application of Z-test homework help online as follows:

  • The sample size is larger than 30. If less than 30 then use a t-test.
  • The data must be distributed normally. For samples greater than 30, this does not matter.
  • Data points must be independent of one another. One data point does not affect or is related to another data point.
  • Sample sizes must be equal
  • You should select data from a population randomly, wherein every item has got an equal chance of getting selected.

Key Differences Between T-Test and Z-Test

The key differences between the two tests are as follows:

  • T-test is a statistical test that can analyze and compare the difference between the means of two population when the standard deviation is unknown. Z-test is an analysis test that is applied when you know the standard deviation.
  • An important condition to adopt t-test is the unknown population variance. Population variance must be assumed or known for z[-test.
  • T-test is t-distribution. Z-test depends on the assumption that the mean of the sample is normal. Both tests appear the same because both are bell-shaped and are symmetrical. However, they differ because, in a t-test, space is less at the center but more in trails.
  • When the sample size is large, z-test is used and when the sample size is small, the t-test is used.

Various Purposes of Z-Test

Z-test is used for the following purposes as mentioned when you ask, “write my assignment on application of z-test”.

  • Z-test for a single proportion is used for testing a hypothesis on a particular value of a population proportion.
  • Z-test for proportion differences for testing the hypothesis where two populations are the same in proportion.
  • Single mean is used for testing a hypothesis on a particular value of a population mean
  • Single variance z-test is used for testing a hypothesis on the particular value of population variance. Unlike the chi-square test, this test is used if the sample is greater than 30.
  • Testing variance equality is used for testing the hypothesis of two population variances that are equal when a sample size of every sample is either 30 or more.
