Standard Deviation Comparisons of Population Sizes

CSEF · 2005 Mathematics & Software

Landon H. Aaker · Terrace Hills Middle School, Grand Terrace

Overview

Objectives/Goals I am trying to determine how large a survey sample must be to get an accurate representation of a whole population. Methods/Materials I rolled a dice 600 times and recorded it then plugged in different sizes of samples of the population into an equation to determine the standard deviation. Results 15% of the whole population will give you an accurate representation. Conclusions/Discussion The smallest sample required for reliable results is 15% of the whole population.

Summary statement

I am trying to determine statistically how large a survey sample must be to get an accurate representation of a whole population.
