What is the Calculated Standard Deviation In The Following Data 13 12 9 15 11 16 17 8 12 7 12?
It is 3.045
What is the mode for data set 11 12 13?
The mode is the data set element(s) that is(are) repeated the most. If every data set element occurs the same number of times, there is no mode. As there is only one occurrence of each data set element in {11, 12, 13} there is no mode. If your data set read {11, 12, 12, 13, 13, 12} your mode would be 12. If your data set read {11, 12, 12, 13, 13} your modes would be 12 & 13.

11
What do you do when you are finding a range of a number?
When finding the range of a set of data, you take the greatest number and subtract the lowest number from it. That's your range! EX: 2,4,5,8,9,13 13-2= 11 11 is your range. Note: The range doesn't have to be a number in the data.

What is the standard deviation of the following data set 8 9 9 9 10 11 11 12?
For 8 9 9 9 10 11 11 12: σ=1.3562
What is the purpose of finding the standard deviation of a data set?
The purpose of obtaining the standard deviation is to measure the dispersion data has from the mean. Data sets can be widely dispersed, or narrowly dispersed. The standard deviation measures the degree of dispersion. Each standard deviation has a percentage probability that a single datum will fall within that distance from the mean. One standard deviation of a normal distribution contains 66.67% of all data in a particular data set. Therefore, any single datum in the data has a 66.67% chance of falling within one standard deviation from the mean. 95% of all data in the data set will fall within two standard deviations of the mean. So, how does this help us in the real world? Well, I will use the world of finance/investments to illustrate real world application. In finance, we use the standard deviation and variance to measure risk of a particular investment. Assume the mean is 15%. That would indicate that we expect to earn a 15% return on an investment. However, we never earn what we expect, so we use the standard deviation to measure the likelihood the expected return will fall away from that expected return (or mean). If the standard deviation is 2%, we have a 66.67% chance the return will actually be between 13% and 17%. We expect a 95% chance that the return on the investment will yield an 11% to 19% return. The larger the standard deviation, the greater the risk involved with a particular investment. That is a real world example of how we use the standard deviation to measure risk, and expected return on an investment.
11 Determines how far away the data values are from the average?
Standard deviation determines how far away the data values are from the average.
What is the standard deviation for 11 13 15 16 20 21?

What is the Calculated Standard Deviation In The Following Data 13 12 9 15 11 16 17 8 12 7 12?
It is 3.045
What does it mean if the standard deviation is equal to the mean?
A large standard deviation indicates that the distribution is heavily weighted far from the mean. Take the following example: {1,1,1,1,1,19,19,19,19,19} Mean is 10 and StDev = 9.49 Now look at this data set: {5, 6, 7, 8, 9, 11, 12, 13, 14, 15} Mean is still 10, but StDev = 3.5
