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.

How does standard deviation depend on a data?
Standard deviation measures the amount of variation or dispersion in a dataset. It quantifies how much individual data points deviate from the mean of the dataset. A larger standard deviation indicates that data points are spread out over a wider range of values, while a smaller standard deviation suggests that they are closer to the mean. Thus, the standard deviation is directly influenced by the values and distribution of the data points.
When the size of a representative sample increases does the mean range median or standard deviation decrease?

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.

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.
Can the value for the standard deviation be larger than the value for the rqange?
Yes, the standard deviation can be larger than the range in certain situations. The range is calculated as the difference between the maximum and minimum values in a dataset, while the standard deviation measures the spread of the data around the mean. If the data points are widely dispersed with a few extreme values, the standard deviation can exceed the range, especially in small datasets.
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 does standard deviation tell us about the data?
Standard deviation measures the dispersion or variability of a dataset by quantifying how much individual data points deviate from the mean. A low standard deviation indicates that the data points are clustered closely around the mean, while a high standard deviation signifies that they are spread out over a wider range. This statistic helps in understanding the consistency of the data and is crucial for interpreting the reliability of statistical analyses.
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.
Why is standard deviation better than range at measuring dispersion?
Standard deviation is generally considered better than range for measuring dispersion because it takes into account all data points in a dataset, rather than just the extremes. This allows standard deviation to provide a more comprehensive understanding of how data points vary around the mean. Additionally, standard deviation is less affected by outliers, making it a more robust measure of variability in most datasets. In contrast, range can be misleading as it only reflects the difference between the highest and lowest values.
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.
