P-value for proposed difference of the mean between 2 samples

Source: R/pval_t2.R

Calculates the p-value for the proposed difference of the mean between 2 samples (t distribution).

pval_t2(x1, s1, n1, x2, s2, n2, dmu = 0, side = c("two", "one"))

Arguments

x1

Sample's 1 mean
s1

Sample's 1 standard deviation
n1

Sample size of sample 1
x2

Sample's 2 mean
s2

Sample's 2 standard deviation
n2

Sample size of sample 2
dmu

Proposed difference between sample means (Default is 0)
side

To either get a two-tail or one-tail p-value (Default is "two")

Value

P-value

Examples

x1 <- 34.67
s1 <- 4.97
n1 <- 15
x2 <- 40.87
s2 <- 5.36
n2 <- 15
pval_t2(x1, s1, n1, x2, s2, n2)
