Standard deviation is a commonly used measure of the variability of a set of measurements.
But that usually refers to a 'normal' distribution - an assumption that the results are distributed according to a 'normal' (Gaussian) curve. There are several other types of distribution, Poisson, Bernoulli, and others.
It is important to note that the application of standard deviation becomes less and less useful as one approaches the extremes of the set of measurements.

What is the most commonly used statistic in Psychology?
Correlation coefficient is a statistic that is commonly used in Psychology. It is a type of descriptive statistic that measures direction and strength in variables.
What does the Wechsler test measure?
The Wechsler test measures cognitive abilities such as verbal comprehension, perceptual reasoning, working memory, and processing speed. It provides a comprehensive assessment of an individual's intellectual functioning and is commonly used to identify strengths and weaknesses in different areas of cognitive functioning.

What is the relational value between PSI and CUP?
There is no direct relationship between PSI (pounds per square inch) and CUP (copper units of pressure) as they are two different units used to measure pressure in different contexts. PSI is commonly used in various industries, while CUP is specifically used in firearms to measure chamber pressure. Conversion between the two units is not straightforward due to the different measurement methodologies.
What instrument measures brain activity?
An electroencephalogram (EEG) is the most common instrument used to measure brain activity by recording electrical patterns in the brain. EEG is non-invasive and helps in diagnosing conditions like epilepsy, sleep disorders, and brain injuries.
Which measure of variability is used most often in conjunction with the mean?
range
What is the most commonly used statistical index of variability in a group of scores is the?
It is the standard error.
What is the most commonly used measure of central tendency?
The mean.
Is the most common encountered measure of variability standard deviation?
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.
What is the most commonly used measure of concentration for an aqueous solution?
The most commonly used measure of concentration for an aqueous solution is molarity, which is the number of moles of solute per liter of solution.
Which is used as an index of precision?
The Coefficient of Variation (CV) is commonly used as an index of precision. It is a measure of relative variability that expresses the standard deviation as a percentage of the mean. A lower CV indicates higher precision and vice versa.
