How To: Use the Empirical Rule w/ standard normal distribution

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...

How To: Calculate sums in standard form

When a number is expressed in the form of x multiplied by 10^y such that, x < 10 and y is an integer, the number is said to be in standard form. Standard form of expressing numbers finds its use in scientific and statistical fields. This video demostrates how to express, as well as perform basic mathematical operations namely, addition/subtraction, multiplication and division of numbers in the standard form using four examples/mathematical problems. The first two examples demostrate multiplic...

How To: Know standard deviation in your financial portfoli

How To: Perform the Slow Flight maneuver

In this AeroCast episode, UND Aerospace discusses the Slow Flight maneuver as performed in the Piper Warrior (PA-28-161), referencing the procedures and standards outlined in the UND Warrior Standardization Manual. All performance tolerances are based on the performance standards set forth by the FAA Private Pilot Practical Test Standards. Since the most critical phases of flight occur at airspeeds less than cruise, a pilot must always be comfortable with his or her airplane’s handling charac...

How To: Perform Power On Stall maneuvers

In this AeroCast episode, Anthony Bottini discusses the Power On Stall maneuver as performed in the Piper Warrior (PA-28-161), referencing the procedures and standards outlined in the UND Aerospace Warrior Standardization Manual. All performance tolerances are based on the performance standards set forth by the FAA Private Pilot Practical Test Standards. Power On Stall practice is vital in increasing a pilot’s proficiency in regards to stall recognition and stall recovery techniques during an...

How To: Convert numbers in and out of standard form

In this video, we learn how to convert numbers in and out of standard form. Standard form is a useful way of writing down very large numbers and very small numbers. To do this, you will look at the number you have and ignore the zeros that are just at the end. Then, write down the basic numbers. Put a decimal point in this number to make it between one and ten. Now, write down x 10 and put the power for how many places the decimal point moved to get to the new number. This will help you write...

How To: Calculate standard deviation

Looking to find the standard deviation of your set of values? Standard deviation quantifies how diverse the values of your data set are, and is useful in determining how different your numbers are from each other.

How To: Understand mean and standard deviation

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...

How To: Compare 2 distributions with the Z-Score formula

This is a video tutorial in the Education category where you are going to learn how to compare 2 distributions with the Z-Score formula. 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...

How To: Find the standard error of the mean

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...

How To: Create standard content layouts by nested master pages

In this ASP.Net video tutorial, Chris Pels will show how to use nested master pages to create individual master pages that represent different standard content layouts for a web site. First, see how several major commercial web sites use a standard set of content layouts. Next, see how to nest a master page within another master page, and use the design time support in Visual Studio 2008. Then, learn the considerations for establishing a “page architecture” which represents the major types of...

How To: Interpret a standard deviation

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...
