OBGYN MSc Stat Module (2016-2018)
StatPgm 1. Probability of z and t
Please note : the data presented in all course material for the statistical module are generated by computers to demonstrate the methodologies, and should not be confused with actual clinical information
Also : Programs can have default example data pre-inserted, or inserted when the Example button is clicked, for testing. Students can replace them with his/her own data
1a. Probability of z
Calculate probability from z : The z value is entered in the text box, and the result is probability
Calculate z from probability : The probability value is entered in the text box, and the result is z
z value :
Probability value :

1b. Probability of t :
Calculate probability of t and its degrees of freedom    The t and df values are entered in the text boxes    Results are Probabilities of 1 and 2 tail model.
Calculate t from probability and degrees of freedom    The probability and df values are entered in the text boxes    Results are t for 1 and 2 tail model
t value : degrees of freedom :
Probability value : degrees of freedom :

1c. Relating Values and Percentiles Based on the t Distribution
Calculate value from percentile : Enter n, mean, and Standard Deviation, then value. Result is the percentile
Calculate percentile from a value : Enter n, mean, and Standard Deviation, then percentile. Result is the value
n : mean : Standard Deviation :
Percentile :
Value :
