A Population
The average of a set of data is known as its "mean."
The data set must be unbiased, the outcomes of the trials leading to the data set must be independent. The data set must be large enough to allow the Law of Large Numbers to be effective.
The mean of a set of data is also known is the average.
The mean!
a database
This is known as a skewed data set.
No. Here's one set of data where the mean is not one of the values: a set of 250,000 numbers. 125,000 of them are "1", 125,000 are "3". The mean of this data set is "2", which is not among the data.
It gives a measure of the spread of the data.you
A number does not have a quartile, a set of data does. The lower quartile of a set of data set is a value, in the data set, such that a quarter of the date set are smaller and three quarters are larger. The upper quartile is defined similarly. The middle quartile, better known as the median, divides the data set in two.
A large range in a data set indicates a significant difference between the highest and lowest values, suggesting considerable variability or dispersion within the data. This can imply that the data points are widely spread out, which may reflect diverse underlying factors or conditions. Additionally, a large range can highlight potential outliers or extreme values that may influence the overall analysis.
Data that does not fit with the rest of a data set is known as an outlier. Outliers can skew statistical analyses and distort the interpretation of data. They can be caused by errors in data collection, measurement variability, or may represent true but rare occurrences in the data set. Identifying and handling outliers appropriately is crucial in ensuring the accuracy and reliability of data analysis results.
