A t-test is one of the most popular statistical tests for location, i.e., it deals with the population(s) mean value(s). There are different types of t-tests that you can perform: A one-sample t-test; A two-sample t-test; and A paired t-test. In the next section, we explain...
In a one-sample t-test, we take a small sample of data from a large population. For example, a small sample of 10 students from a large population of 150 students. The formula then takes the average of a small sample and compares it with the average of the population to check if the...
1–This implies that a paired samples t-test is to be performed. 2–This implies that a two-sample equal variance t-test is to be performed. One must perform this test when there are two independent samples having the same (equal) population variances. The feature of the same variance is...
Describes the t-test formula for one-sample, two-independent samples and paired samples t-test. One Sample T-Test Formula 3 mins Alboukadel Kassambara Describes the one sample t-test formula, which is used to compare the mean of one sample to a known standard mean. ...
Paired sample t-test What is paired t-test ? Paired Student’s t-testis used to compare the means of two related samples. That is when you have two values (pair of values) for the same samples. For example, 20 mice received a treatment X for 3 months. The question is to test whet...
Apply T.TEST to get the difference. The first test is a type of Paired. The result is 0.04059. The second test is a type of Two Samples equal variance. The result is 0.2148. The third test is a type of Two Sample unequal variance. ...
Type(It is a required argument) – The type of t-test to perform: 1– Performs a paired t-test. 2– Two-sample equal variance t-test. 3– Two-sample unequal variance t-test. How to Use the T-TEST Function in Excel? To understand the uses of the T.TEST function, let’s consider...
Moss and Fangio were paired at Le Mans and held an easy lead when the team withdrew. One of its drivers, Pierre Bouillon, who raced under the nom-de-guerre, 'Pierre Levegh' had been involved in an accident not of his making. His car was launched into the crowd, killing the unfortunat...
There was no statistical difference between the predicted value and the measured value using the paired sample t test (t = 0.034, P = 0.973). Discussion The spinal regions (the pelvis and the lumbar, thoracic, and cervical regions) are not independent of one another, and they have...
ANOVA, the chi-square test, and the t-test were used for outcome assessments. Results The post-test IIFAS-J score was significantly higher than the pre-test score only for Group 1 (p < 0.01). The percentage of participants who agreed with the content of the text was 70.7% in ...
