The t distribution calculator and t score calculator uses the student's t-distribution.The Student's t-distribution is an artificial distribution used for a normally distributed population, when we don't know the population's standard deviation or when the sample size is too small....
Before the lockdown, the population mean was 6.5 hours of sleep. The lockdown sample mean is 7.62.To assess whether your sample mean significantly differs from the pre-lockdown population mean, you perform a z test:First, you calculate a z score for the sample mean value. Then, you find...
Note:The t-distribution calculator only reports cumulative probabilities (e.g., the probability that a t score is less than or equal to a specified value.)
