Variance, standard deviation and standard error are the most common but there are also
mean absolute error,
standardised error
range
inter-quartile range
The use of "error" does not mean that anything is wrong - the expression simply means difference from the expected value.
the whole question is that The data is not perfectly linear. Identify at least 2 sources of variability in this data AND explain the effect of each? Sources of variability = outlier???? so do I just need to indicate where the outliers are???
In math, a common factor usually refers to a factor that two or more numbers have in common. But, if you mean the most frequently occurring factor, that would be different. Since 1 divides every number, it would be the most common (frequently occurring) factor.
The slope of a line measures the steepness of the line.

There are many theories and formulas that can be applied to find the length of each of the sides of a triangle. The most common is the Pythagorean Theorem: a2+b2= c2 . The letters: "a , c" are the two legs. The hypotenuse is the letter "c". For a 30-60-90 triangle you can use a special formula, as well as a 45-45-90 triangle.
Why are measures of variability essential to inferential statistics?
The usual measures of variability cannot.
The best measure of variability depends on the specific characteristics of the data. Common measures include the range, standard deviation, and variance. The choice of measure should be made based on the distribution of the data and the research question being addressed.
The range, inter-quartile range (IQR), mean absolute deviation [from the mean], variance and standard deviation are some of the many measures of variability.
It measures the error or variability in predicting Y.
The most commonly encountered measure of variability is indeed the standard deviation, as it provides a clear indication of how much individual data points deviate from the mean in a dataset. It is widely used in statistical analysis because it is expressed in the same units as the data, making it easy to interpret. However, other measures of variability, such as range and interquartile range, are also important and may be preferred in certain contexts, particularly when dealing with non-normally distributed data or outliers.
In mathematics, variability refers to the extent to which a set of data points differ from each other. It indicates how spread out or clustered the values are around a central tendency, such as the mean. Common measures of variability include range, variance, and standard deviation, which help quantify the degree of dispersion in a dataset. Understanding variability is crucial for analyzing data and making informed conclusions.
Descriptive measures are most often used when summarizing and presenting data in a clear and concise manner. They provide insights into the central tendency, variability, and overall distribution of a dataset, making it easier to understand patterns and trends. Common applications include reporting statistics in research studies, analyzing survey results, and summarizing performance metrics in business. These measures help stakeholders make informed decisions based on the data at hand.
The most common instrument (tool) is a tape measure.

Biodiversity measures the variety and variability of life forms within a given area. It includes diversity at the genetic, species, and ecosystem levels.
