Question

Calculate the standard deviation of given date plant
Height (cm) X 2,3,6,5,9

Answer 1

Answer:

2.45

Step-by-step explanation:

Mean=(2+3+5+6+9)/5

=5

standard deviation=

$\sqrt{ \frac{sigma {(xi - m)}^{2}}{n} }$

where sigma means summation

xi means observation

m means mean

and n means number of observations

so we get by substituting values

$\sqrt{6}$
