What are the mean median mode range and standard deviation of the dataset 76 82 73 93 91 81 79 86 84?
To calculate the mean, add all the numbers (76 + 82 + 73 + 93 + 91 + 81 + 79 + 86 + 84 = 765) and divide by the total count (9), resulting in a mean of 85. The median, when the numbers are arranged in order (73, 76, 79, 81, 82, 84, 86, 91, 93), is 82. The mode does not exist as all numbers appear only once. The range is 93 - 73 = 20, and the standard deviation is approximately 6.07.

What is 1standard deviation below 100?
The standard deviation varies from one data set to another. Indeed, 100 may not even be anywhere near the range of the dataset.

What is the relationship between standard deviation and mean?
The standard deviation and mean are both key statistical measures that describe a dataset. The mean represents the average value of the data, while the standard deviation quantifies the amount of variation or dispersion around that mean. A low standard deviation indicates that the data points are close to the mean, while a high standard deviation indicates that they are spread out over a wider range of values. Together, they provide insights into the distribution and variability of the dataset.

Which measure of variation is appropriate when using the mean and which is appropriate when using the median?
When using the mean: the variance or standard deviation. When using the median: the range or inter-quartile range.
What is best Interquartile range or Median absolute deviation?
The answer depends on the purpose. The interquartile range and the median absolute deviation are both measures of spread. The IQR is quick and easy to find whereas the MAD is not.
What do you mean by measures of central tendency and dispersion?
Common measures of central tendency are the mean, median, mode. Common measures of dispersion are range, interquartile range, variance, standard deviation.
Definition of descriptive statistic?
A descriptive statistic describes the characteristics of a known set of data; such as mean, median, mode, range, standard deviation and so forth.

Which value is NOT always a number in the data set it represents?
The range, median, mean, variance, standard deviation, absolute deviation, skewness, kurtosis, percentiles, quartiles, inter-quartile range - take your pick. It would have been simpler to ask which value IS in the data set!
What is the range of standard deviation of 18 15 12 13 17 14 19 20 8?
The range is 12 and the standard deviation is 3.822448314.
Does an outlier have a greater effect on the standard deviation or interquartile range?
On the standard deviation. It has no effect on the IQR.
