Sample Size Sample size determination is the act of choosing the number of observations or replicates to include in a statistical sample. The BIGGER the sample size, the better the chance it will give ACCURATE results. Margin of Error Confidence interval, tells you how reliable your surveys are. The higher MOE, the more inaccurate the results are. The lower MOE, the more accurate the results are. A good rule is that if the difference between two numbers or percentages is smaller than the ...

what is absolute value? correct answers distance from zero on a number line if you get a negative absolute value, why is it said to not have a solution? correct answers because distance can't be negative what are integers? correct answers all whole negative and positive numbers when should u switch the sign on an inequality? correct answers when you're dividing or multiplying by a negative number why is it that you can have a both negative and positive solution for absolute value? ...

quantitative data - Answer Quantitative data consists of data values that are numbers, representing quantities that can be counted or measured. The Empirical Rule - Answer According to The Empirical Rule, approximately 68% of the data points in a dataset will be within 1 standard deviation of the mean. 95% of all values are within 2 standard deviations of the mean. Normal distribution - Answer In a normal distribution data is symmetrical, so the mean, median, and mode are all equal. mea...
