The conditions required to conduct the t-test include the measured values in ratio scale or interval scale, simple random extraction, normal distribution of data, appropriate sample size, and homogeneity of variance.
What are the three assumptions of a twoTwo-sample t-test assumptions
Data in each group must be obtained via a random sample from the population. Data in each group are normally distributed. Data values are continuous.
Which of the following is not required to apply the tAnswer and Explanation: For performing a t test, we don't need to know the population standard deviation.
Which of the following is an assumption of hypothesis testing?Statistical hypothesis testing requires several assumptions. These assumptions include considerations of the level of measurement of the variable, the method of sampling, the shape of the population distri- bution, and the sample size.
