Error (statistical error) describes the difference between a value obtained from a data collection process and the 'true' value for the population. The greater the error, the less representative the data are of the population. Data can be affected by two types of error: sampling error and non-sampling error.

Explanation:
The question is asking for the number of errors in the Statistics area, and the correct answer is option 'B' which states that there are two errors.
Statistics is the branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It is a very important subject in the field of business, science, and social sciences.
To understand why the number of errors in the Statistics area is two, we need to look at some possible scenarios:
- Scenario 1: The question is referring to a specific dataset or study in the field of Statistics, and there are two errors in that dataset or study. For example, there could be two incorrect data points or two mistakes in the statistical analysis.
- Scenario 2: The question is referring to the general field of Statistics, and there are two common errors that students or researchers make in this field. Some examples of common errors in Statistics include:
* Misinterpreting statistical significance: Statistical significance does not necessarily mean practical significance. In other words, just because a result is statistically significant does not mean it is meaningful or important in real-world terms.
* Confusing correlation with causation: Correlation means that two variables are related or associated with each other, but it does not necessarily mean that one variable causes the other.
* Using inappropriate statistical tests: Different statistical tests are appropriate for different types of data and research questions. Using the wrong test can lead to incorrect conclusions.
* Failing to check assumptions: Many statistical tests have assumptions that must be met in order for the test to be valid. Failing to check these assumptions can lead to incorrect results.
* Data cleaning errors: Before conducting statistical analyses, data must be cleaned and checked for errors or outliers. Failing to do so can lead to incorrect conclusions.
In conclusion, the question is likely referring to a specific scenario or common errors in the field of Statistics, and the correct answer is that there are two errors.
