Complete standard deviation calculations for statistical population samples from Leaf Lab
Standard Deviation formula
where,
s = sample standard deviation
= sum of...
= sum of... x = individual value from sample group
x bar= sample mean (average)
n = number of values in sample group
x bar= sample mean (average)
n = number of values in sample group
Calculate standard deviation for length and width of the following sample groups:
Group A: leaves taken from a tree located within 10 meters of a busy road
Group B: leaves taken from a tree located at least 20 meters away from a busy road
