simple math question rewritten so some of the dimmer can understand it
Let me rephrase the question.
given a list of measurements for a single quantity which strategy provides the most likely best estimate of the true value.
1 Averaging the measurements
2 Averaging the measurements then applying the rules of significant digits to the average
Which answer is most likely closer to the true answer ??
Maybe an example would help.
If a civil engunear weighed his collection of pet rocks every day for five days for a graduate lab course in rock weighing which value should he report to his perfessur for the weight of his rock collection.
A pick the number he likes cause its purty.
B Average the weights he recorded and report this.
C Apply the rules of significant digits to the average from B and report this.
D Any other option for the 5 readings
E Leave the rocks in his head and insist that the Perfessur told him that his rock arrangement would lead to a persistent bias so he might as well not bother doing his work and should simply continue posting right-wingnut twaddle on financial message boards as he has non-stop for at least the last twelve years.
One would think that such a talented business leader could find more productive use of his time.
Only two conclusions are possible.
1 He is talented but doesn't believe in his talent so he underachieves and wastes his time here.
2 He fails at everything else and the message board is his fallback.
Somebody must be copy pasting for you. I've got a very good measurement of how dim your bulb is from reading previous posts. It is readily apparant that after you run out of fingers and toes, numbers don't mean anything to you.
