What type of error does the mean value of the measurement help us detect? Explain.
What type of error does the mean not help us detect? Explain.
In regards to systematic or random errors.
Homework Answers
Random errors are fluctuations in measurement due to precision issues. Random errors don't change all the measurements from the true value. Random errors can be detected by mean. Mean of all the measurements give a value that is associated with or nearer to the measurements. Random errors can be detected by mean as they are farther away from the value of mean.
Systemic errors are errors throughout the measurement. All the measurement values are away from the true value in the same scale. This can be due to calibration mistake. Systemic errors cannot be detected by mean as mean would also be in the same range.

1-The answer is true or false a-Random errors arise from both measurement errors and sampling variation. True False b-Sampling variability stems from inaccuracies in assessing the exposure and disease occurrence. True False c-Just like bias and confounding, random errors are considered systematic errors. True False d- In addition to the p-value, the confidence interval is another method for estimating the amount of random error in epidemiological studies. True False
