Covariance-based SEM estimates model parameters using the empirical variance-covariance matrix, and it is the method of choice if the hypothesized model consists of one or more common factors. Two types of SEM can be distinguished: covariance- and variance-based SEM. Its ability to model latent variables, to take into account various forms of measurement error, and to test entire theories makes it useful for a plethora of research questions. Structural equation modeling (SEM) is a family of statistical techniques that has become very popular in business and social sciences.

In the normally distributed sampling distribution, the sample mean, quantiles of the normal distribution and standard error can be used in the calculation of the population mean’s confidence intervals.Copyright © 2016, Authors. Additionally, the sample standard deviation will also become approximately equal to the population standard deviation with the increase in sample size. In the case of finite population standard deviation, an increase in sample size will eventually reduce the standard error of the sample mean to zero as the population’s estimation will improve. So, standard error helps estimate how far the sample mean from the true population means. Statisticians usually use the sample from a large pool of data as it is difficult to process such a huge data set, and as such, sampling makes the task a lot easier. It is very important to understand the concept of standard error as it predominantly used by statisticians as it allows them to measure the precision of their sampling method. Standard Error = s / √n Relevance and Use of Standard Error Formula Step 5: Finally, the formula for standard error can be derived by dividing the sample standard deviation (step 4) by the square root of the sample size (step 2), as shown below. Step 4: Next, compute the sample standard deviation (s), which involves a complex calculation that uses each sample variable (step 1), sample mean (step 3) and sample size (step 2) as shown below. It is denoted by, and mathematically it is represented as, Step 3: Next, compute the sample mean, which can be derived by dividing the summation of all the variables in the sample (step 1) by the sample size (step 2). Step 2: Next, determine the sample size, which is the total number of variables in the sample.
The sample variables are denoted by x such that x i refers to the i th variable of the sample. Step 1: Firstly, collect the sample variables from the population-based on a certain sampling method. The formula for standard error can be derived by using the following steps: Therefore, the standard error of the sample mean is 0.77.
Standard Error is calculated using the formula given below
