A simple online statistical significance calculator to calculate the value of the Comparative error, difference and statistical significance for the given sample size and percentage response. The statistically significant result is attained when a p-value is less than the significance level. It is represented using the symbol (α), alpha. The statistical significance is used in hypothesis testing to find if a data is statistically significant.
Consider 2 groups, one having 10 people and the other has 8. The percentages to compare are 5% for the group of 10 and 9% for the group of 8. Find the statitical significance of the given sample.
r1 = 5, s1 =10, r2 = 9, s2 = 8
Comparative Error = 1.96 x √[5 (100-5) / 10] + [9(100-9)/8]
= 1.96 x √[475/10] + [81/8]
