Measures of In this lesson, we're looking at the measures of central tendencies. The measures of central tendency provide us with statistical information about a set of data. The four primary measurements that we use are the mean, median, mode and range. Each one of these measurements can provide us with information about our data set.

This information can then be used to define how the set of are connected. To really examine these data points, let's take a look at a football game between the Green River Ducks and the Southland Bears. Mean The first measure is the mean, which means average. To calculate the mean, add together all of the numbers in your data set.

Then divide that sum by the number of addends. For example, let's look at the Bears' first offensive series. They had plays of 16, 14, 12 and 18 yards on their way to scoring a touchdown. To find the average number of yards, or the mean, we would first add all four of these values together: 16 + 14 + 12 + 18 = 60. Since there were four numbers in our data set, you would divide that sum by 4: 60 ÷ 4 = 15.

Mean Median Mode In Java Codes and Scripts Downloads Free. Statistical Calculator calculates minimum, maximum, mean, median, mode.

So, the average number of yards that the Bears gained was 15 yards. The mean is used to show us the true average of a set of data. Median Another measure of central tendency is the, which is the middle number when listed in order from least to greatest. You may have heard the word median before, and it was likely on a highway. On a highway, you have opposite lanes of traffic. In the middle of the lanes, there is typically a grassy area or a turning area. This area in the middle of the highway is referred to as a median.

Let's return to our game in progress and see how the Green River Ducks are doing. On the Ducks' first offensive series, they had plays of 10, 6, 19, 21 and 4 yards before scoring a touchdown. Let's find the median number of yards gained by the Ducks. The first thing you need to do with this list of yardages is put the numbers in order from least to greatest. So, in order from least to greatest, we would have 4, 6, 10, 19 and 21. Fsx Slovakia Scenery more.

Now that your yardages are in order from least to greatest, find the middle number. Since there are five numbers, the middle number would be the third value.

The median value of this set of data is 10. On the first offensive series for the Ducks, their median yards gained were 10 yards. Occasionally there may be an even number of values, which would provide you with two numbers in the middle. If this occurs, you will need to average the two values. At halftime of our game, the Bears quarterback has passes of 3, 8, 9, 12, 12 and 15 yards. Let's find the median pass thrown by the Bears quarterback. The first step is to make sure your numbers are in order from least to greatest, which they are in this problem.
