The statistic that describes the variation in a data set is called the "variance." Variance measures how far each data point in the set is from the mean and from each other. A higher variance indicates that the data points are more spread out, while a lower variance suggests they are closer to the mean. The standard deviation, which is the square root of the variance, is also commonly used to express variation.
It is a measure of the spread of the data around its mean value.

which measure best describes the data set
The statistic that describes the variation in a data set is called the "variance." Variance measures how far each data point in the set is from the mean and from each other. A higher variance indicates that the data points are more spread out, while a lower variance suggests they are closer to the mean. The standard deviation, which is the square root of the variance, is also commonly used to express variation.
This statement is incorrect. If data set A has a larger standard deviation than data set B, it indicates that data set A is more spread out, not less. A larger standard deviation reflects greater variability and dispersion of data points from the mean, while a smaller standard deviation suggests that data points are closer to the mean and thus less spread out.
It gives a measure of the spread of the data.
The data set whose inter-quartile range is the largest.
A data set that describes the colors of cars in a parking lot would be classified as qualitative data. This is because the data is descriptive and categorical in nature, rather than numerical or measured.
Yes, if data set A has a larger standard deviation than data set B, it indicates that the values in data set A are more spread out around the mean compared to those in data set B. A higher standard deviation signifies greater variability and dispersion in the data. Conversely, a smaller standard deviation in data set B suggests that its values are more closely clustered around the mean.
bimodal
It is one of the key measures of a data set: it shows the value around which the observations are spread out.
