What does a small absolute deviation tell you about a data set?
It means that particular observation is close to the population [or sample] mean.
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.
How do you identify group data or ungroup data in standard deviation?
You cannot. If you are told the standard deviation of a variable there is no way to tell whether that was derived from grouped or ungrouped data.
What does a standard deviation of 0 tell you?
The smaller the standard deviation, the closer together the data is. A standard deviation of 0 tells you that every number is the same.
What does standard deviation tell about distribution?
How widely spread out, or tightly concentrated about the mean it is.
What does the mean absolute deviation tell you about how spread out the data are?
i dont know...... it means
What does the mean absolute deviation tell you about a set of data?
It is a measure of the spread or dispersion of the data.
What does a small absolute deviation tell you about a data set?
It means that particular observation is close to the population [or sample] mean.
What does the mean adsolute deviation tell you about a data set?
it tells you
Why is the mean the standard partner of the standard deviation?
The mean and standard deviation often go together because they both describe different but complementary things about a distribution of data. The mean can tell you where the center of the distribution is and the standard deviation can tell you how much the data is spread around the mean.
What can a standard deviation tell us about the usefulness of the mean?
Standard deviation measures the dispersion or variability of data points around the mean. A low standard deviation indicates that the data points are closely clustered around the mean, suggesting that the mean is a reliable representation of the dataset. Conversely, a high standard deviation signifies greater variability, which may diminish the mean’s usefulness as a summary statistic, as it may not accurately reflect the data's central tendency. Thus, understanding standard deviation helps assess how well the mean represents the underlying data.

What would the Z score be if Z equals 0 and Z equals -1.41?
1.41
Advantages and disadvantages of mean deviation?
The mean deviation is a measure of dispersion that calculates the average absolute difference between each data point and the mean. One advantage of mean deviation is that it considers every data point in the calculation, providing a more balanced representation of the data spread. However, a disadvantage is that it can be sensitive to outliers, as it does not square the differences like the variance does in standard deviation, making it less robust in the presence of extreme values.
How do you identify group data or ungroup data in standard deviation?
You cannot. If you are told the standard deviation of a variable there is no way to tell whether that was derived from grouped or ungrouped data.
What does the standard deviation tell us about the mean?
The standard deviation tells us nothing about the mean.
What does a standard deviation of 0 tell you?
The smaller the standard deviation, the closer together the data is. A standard deviation of 0 tells you that every number is the same.
