Find the range, standard deviation, and variance for the given sample. -10, -25, -5, -14, -27, -18, -9 The mean is 71 and the standard deviation is 9. What is the z value of the value 66? How to find probability for an exact number with standard deviation?
Explain how to find mode given the mean and standard deviation. Mean, Standard Deviation, and Mode of a Data Set: The mean of the data set is the average, the standard deviation of a data set shows how varied the data points are (how far apart they lie), and the mode of a...
To calculate variance, we find the average of the squared differences between each data point and the mean. Standard Deviation: Standard deviation, on the other hand, is the square root of the variance. It tells us the average amount of deviation or spread of the data points from the mean...
A low standard deviation indicates that the data are close to the mean, whereas a high standard deviation indicates that the data are spread further away from the mean. Example data For this example, let’s say I’ve measured the weight of 10 female bulldogs of a similar age. Below are ...
Step 3:Click the variables you want to find the standard deviation forand then click “Select” to move the variable names to the right window. Step 4:Click the “Statistics” button. Step 5:Check the “Standard deviation” boxand then click “OK” twice. The standard deviation will be ...
To findSample Variance (σ^2), enter the following formula: =F13/(F11-1) F13=Sum of the square of the deviation about the mean (X-μ)^2 F11=Total number of data Enter the following formula to get theStandard Deviation from Sample Variance: ...

Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean. Leant how to find the mean here.
