Answer #1

Let us say there are 5 people with weights (in kg)

70,76,85,49 and 77

You know what a mean is- The average of these 5 weights

However, upon observation you can see that the value 49 is distant from the other 4 observations and there is a significant difference when compared to the average of these 5 observations

So, we call this value a deviation from normal course

Standard Deviation is a measure to quantify this deviation in a dataset. So, Standard Deviation measures the amount of variance in a data set

Let me know if you need anything else, if not please don't forget to like the answer :)

One of the concepts that is key to understanding statistics is standard deviation. Standard Deviation is a measurement of how varied or similar your data is - so if you have outliers, this will mean that you will have a larger standard deviation. Standard deviation is the square root of the variance. The variance (σ2) is a measure of how far each value in the data set is from the mean. Here is how it is defined: 1.   Subtract the mean...

Height data, collected from a statistics class, has a mean x=68.21 inches, and a standard deviation of s= 4.01 inches. The sample size of the data was n=36 . Suppose the data collected could be considered a random sample of UCLA students. What sample size would be needed for a 90% confidence interval to have a margin of error,B , within .25? Give your answer as a whole number.
