Which set has the smallest standard deviation?
It is graphically clear that the data values in Set C are close to the mean and that is why this set has the smallest standard deviation. The graphs on the number line of set A and B shows that data in Set A is more dispersed than the data in set B, hence the standard deviation is set A is larger than of set B.
What is the mean and standard deviation of the data set?
The mean of a set of data values is equal to μ and its standard deviation is equal to σ. If all the data values in the set are increased by the same value k, what is the mean and the standard deviation after the increase?
What is standard deviation in simple words?
Standard Deviation of a Data Set Definition of the Standard Deviation The standard deviation is a measure of how close the data values in a data set are from the mean. It is a quantity that is small when data is distributed close to the mean and large when data is far form the mean.
What do the range and standard deviation have in common?
The range and the standard deviation are both measures of distance. T or F? If the highest score in a distribution is X = 16 and the lowest is X = 4, then the range is 12 or 13 points.
Which data set has the lowest standard deviation?
The smallest possible S.D. is 0 - and that's when all of the numbers in a group are the SAME. Based on that last concept, the smallest S.D.
Which has the smaller standard deviation How do you know?
Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out. A standard deviation close to zero indicates that data points are close to the mean, whereas a high or low standard deviation indicates data points are respectively above or below the mean.
How do you find the largest and smallest standard deviation?
0:043:49Visually assessing standard deviation | AP Statistics | Khan AcademyYouTubeStart of suggested clipEnd of suggested clipSo the largest standard deviation which we want to put on top would be the one where typically. OurMoreSo the largest standard deviation which we want to put on top would be the one where typically. Our data points are further from the mean and our smallest.
Which data set has the greatest standard deviation?
The more spread out a data distribution is, the greater its standard deviation. Interestingly, standard deviation cannot be negative. A standard deviation close to 0 indicates that the data points tend to be close to the mean (shown by the dotted line).
What is small standard deviation?
Basically, a small standard deviation means that the values in a statistical data set are close to the mean (or average) of the data set, and a large standard deviation means that the values in the data set are farther away from the mean.
How do you compare standard deviations?
Comparison of variances: if you want to compare two known variances, first calculate the standard deviations, by taking the square root, and next you can compare the two standard deviations. In the dialog box, enter the two standard deviations that you want to compare, and the corresponding number of cases.
Which histogram has the smallest standard deviation?
In the first histogram, the largest value is 9, while the smallest value is 1. The overall range of data is 9 - 1 = 8. In the second histogram, the overall range is 7 - 3 = 4. The range is larger for Histogram 1....Standard Deviation.Length (X)Deviation from Average (X- X)88 - 4.8 = 3.24 more rows
How do you find the largest standard deviation?
The sample deviation is maximized when half of the observations are at each extreme. If you want a formula for the maximum standard deviation as a function of the interval endpoints and the number of samples, you will probably want to divide the formula up depending on whether the number of samples is even or odd.
Answer
Standard deviation helps in measuring how spread out the values actually are. Without solving for the standard deviation, the smallest standard deviation of the given data sets can be easily guessed.

What is standard deviation?
The Standard Deviation is a measure of how spread out numbers are. According to your data you can consider how spread objects are, how spread people are, how spread heights are, how spread weights are…etc. Its symbol is σ (the greek letter sigma) Lets take an example of heights of dogs.
What is deviation in statistics?
A deviation is a data point’s distance from the distribution mean. If all points in the distribution are the same, then the mean is the same as each distribution point. As such, there are no deviations and the standard deviation is 0. The Rock admits this was the best decision he ever made.
