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 sample standard deviation calculator if we do it infinite times then we can obtain the sampling distribution of the sampling mean. For the example he 1 var stats 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 these deviation which he says that is the https://www.youtube.com/watch?v=ttxR_awbHF0 variance of the sample mean. He says that the variance of the sample distribution will be the ratio of the variance of the original distribution and the number of samples. Now using these values he goes on and explains about the standard error of the mean and other similar concepts. This video gives a good introduction to the concepts of mean, variance and also standard error of the mean.

the standard deviation of a dataset by hand! So what is left for the rest of us level headed folks? Statisticians typically use software like R or SAS, but in a classroom there isn't always http://www.mathbootcamps.com/how-to-find-the-standard-deviation-and-variance-with-a-graphing-calculator-ti83-or-ti84/ access to a full PC. Instead, we can use a graphing calculator to perform http://brownmath.com/ti83/dstats.htm the exact same calculations. Standard Deviation on the TI83 or TI84 For this example, we will use a simple made-up data set: 5, 1, 6, 8, 5, 1, 2. For now, I won't talk about whether we will treat this as population data or sample data but we will get to that in a couple of how to steps. Also, while there is A LOT to talk about as far as interpretation, we will just focus on how to get the calculations down for now. Enter your data into the calculator. This will be the first step for any calculations on data using your calculator. To get to the menu to enter data, press [STAT] and then select 1:Edit. Now, we can type in each number into L1. After how to find each number, hit the [ENTER] key to go to the next line. The entire dataset should go into L1. Calculate 1-Variable Statistics Once the data is entered, hit [STAT] and then go to the Calc menu (at the top of the screen). Finally, select 1-var-stats and then press [ENTER] twice. Select the correct standard deviation Now we have to be very careful. There are two standard deviations listed on the calculator. The symbol Sx stands for sample standard deviation and the symbol stands for population standard deviation. If we assume this was sample data, then our final answer would be . Pay attention to what kind of data you are working with and make sure you select the correct one! In some cases, you are working with population data and will select . What About the Variance The variance does not come out on this output, however it can always be found using one important property: Variance = So in this example, the variance is . This would work even if it was population data, but the symbol would be . standard deviation, TI83/84, variance Keep up to date! Get an email whenever new content is added to MathBootCamps!

Descriptive Statistics for a Frequency Distribution Step 1: Enter class marks in L1 and frequencies in L2. Step 2: Compute the statistics. Step 3: Find the variance.

Seealso: optional advanced material: MATH200B Program part1 gives a downloadable program that computes skewness and kurtosis, two numerical measures of shape Descriptive Statistics for a List of Numbers Quiz scores in a (fictitious) class were 10.5, 13.5, 8, 12, 11.3, 9, 9.5, 5, 15, 2.5, 10.5, 7, 11.5, 10, and 10.5. It's hard to get much of a sense of the class by just staring at the numbers, but you can easily compute the common measures of center and spread by using your TI-83 or TI-84. Step 1: Enter the numbers in L1. By the way, this note uses list L1, but you can actually use any list you like, as long as you enter the actual list name in the 1-VarStats command in Step 2. (It doesn't matter whether there are numbers in any other list.) Enter the data points. [STAT] [1] selects the list-edit screen. Cursor onto the label L1 at top of first column, then [CLEAR] [ENTER] erases the list. Enter the x values. Step 2: Compute the statistics. Select the 1-VarStats command. [STAT] [►] [1] pastes the command to the home screen. Specify which statistics list contains the data set. Show your work: write down 1-VarStats and the list name. Assuming you used L1, enter [2nd1 makes L1]. Press [ENTER] to execute the command. The important statistics are sample size n=15 Always check this first to gua
