In this tutorial, we learn how to know what standard deviation is in your portfolio. Standard deviation is the amount of risk you have inside your portfolio, this will show you how much fluctuation you have in your portfolio. Depending on the expected return of your portfolio over an amount of time, you could have a different range of standard deviation. Knowing what your standard deviation can help you do the math to see what your chances of a return or loss will be for certain. This will he...

This video shows the method to find the variance and standard deviation using Excel. The variance shows the variability of the data points from the median. We find the difference of the median and the mean. We write the formula using '=' sign. The median and data points are put in it by selecting the appropriate cell. The median is made an absolute constant by pressing the F4 key. This is squared by using '^2'. This is multiplied to the frequency using '*'. The result is found for all the dat...
Keith M. Bower explains the meaning of mean and standard deviation. This educational video gives insight in the basics of statistics. The relations between population mean and sample mean and between population standard deviation and sample standard deviation are explained. The mean gives an idea on the central tendency. Standard deviation gives an idea about how spread out the data are. Keith also explains how these two parameters, the joint sufficient statistics, define a normal distributio...
A rough definition of standard deviation is that it is a measure of expressing the observed variations about the average in statistical data i.e. by how much do the observed values vary from the mean. This video continues from the previous solved example and demonstrates the mathematical interpretation of the standard deviation that was calculated. We begin with stating the mean and standard deviation values and then calculating the upper and lower bounds of the data based on the standard dev...
In this video tutorial, viewers learn how to calculate the standard deviation of a data set. The standard deviation of a statistical population, a data set, or a probability distribution is the square root of its variance. To calculate the standard deviation, users will need to follow these steps. 1) Find the mean of the data. 2) Subtract the mean from each data point. 3) Square each of the values you got in step 2. 4) Then find the mean of the values you get from step 3. 5) Finally, square r...
In this video tutorial the instructor explains about the concepts of standard normal distribution and the empirical rule and how to use it to solve an exercise. He starts by explaining about standard normal deviation saying that in a standard normal deviation the value of mean is zero and the value of standard deviation is one. Now he draws the standard normal deviation by drawing a bell curve on an axis. Now he points the mean and standard deviations on it. Now using these concepts he goes o...

In this example Doug's class has X bar as 71 and a standard deviation of 4. Corey's class has X bar as 68 and a standard deviation of 11. If both Doug and Corey beat the class average and have the same standard score, will Doug have a lower grade than Corey? If both of them have a standard score of 1.5, then Doug will get 77 marks and Corey will get 84.5 mar...
In this video the tutor explains about the standard error of the mean. He starts explaining by drawing the diagram of a distribution and now he takes ten samples from the distribution and starts plotting them. He says that in theory if we do it infinite times then we can obtain the sampling distribution of the sampling mean. For the example he takes the number of samples as 10. Now depending on these values of n we can get different sampling distributions. Now he intends to find the mean of t...

Economists have long since known that people want to be rewarded for taking on risk. Investments are thus judged by their risk-adjusted returns (Sharpe ratios). A typical hedge fund has a Sharpe ratio of around 0.5. This means that its excess annual return over the risk-free rate is about half its annual standard deviation.
