I AM GIVING YOU AN EXAMPLE,SO YOU WILL UNDERSTAND IT BETTER
600+470+170+430+300======1970======394
=========================================
YOU HAVE 5 DIGITS SO YOU WILL USE 5
DIVIDE 5 INTO 1970======394YOUR MEAN
SUBTRACT ALL( 5 )
DIGITS FROM YOUR MEAN(394)
VARIANCEσ^2=206^2 + 76^2 + (-224)^2 + 36^2 + (-94)^2
42,436 5,776 50,176 1,296 8,836
YOU WILL MULTIPLY EACH BY ITSELF TO GET YOUR ANSWER 206^2X206^2=42,436
ADD EACH ANSWER YOU WILL GET===108,520
DIVIDE 108,520 BY 5 WHICH WILL EQUAL=======21,704
THIS IS YOUR VARIANCE===21,704
STANDARD DEVIATION IS JUST THE SQUARE ROOT OF YOUR VARIANCE
σ=√21,704=147.32=147
ALL YOU HAVE TO DO IS TYPE IN
√21,704 THEN HIT YOUR EQUAL SIGN GIVES YOU YOUR ANSWER
