1. Statistics might not represent the population 2. Statistics could be subject to a bias 3. Statistics may contain lurking variables

Work Step by Step

1. If a sample population is not representative of the entire population, the statistics may be misleading. 2. If the sampling method is not accurate to the population by means of convenience or response bias, the statistics may be misleading. 3. If two variables are connected through a statistic it does not always imply a relationship. There may be a variable that has gone unnoticed. All three of these issues can cause statistical errors.
