Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean. Leant how to find the mean here.

Sometimes the raw test scores are not informative. For instance, SAT, ACT, and G...
How do you find x-bar in statistics? X-bar in statistics is a symbol for the sample mean. Given a sample of n observations of numbers, the sample mean is found by adding up all of the observations, then dividing by the total number of observations (n). What is the difference between...
To find the y-value for a given x-value between two points, start by finding the slope between the two provided points. Next, use this slope and one of the two points to create an equation in point-slope form. Lastly, substitute the desired x-value and solve for y....
If T-test Value > Critical Value, we reject the null hypothesis. Result: #2 Two-Sample t-Test Formula In a two-sample t-test, we can compare the mean of two different groups. These two groups can either be related or different from each other. For example, we can use it to compare...
Put the data set in ascending order. This can be done with software such as Excel, or by hand (for smaller distributions). Use the formula for percentile, and find the appropriate value in the sorted data set. Recall that the formula for finding the {eq}p^{th} {/eq} percentile of ...

Finding the point estimate depends on which parameter is being estimated. Population parameters are estimated using sample statistics. For example, the sample mean is used to estimate the population mean, and the sample standard deviation is used to estimate the population standard deviation. What is...
Find the mean for the x-variable and find the mean for the y-variable. Subtract the mean of the x-variable from each value of the x-variable. Repeat this step for the y-variable. Multiply each difference between the x-variable mean and x-variable value by the corresponding difference rel...
In statistics, variance measuresvariabilityfrom the average or mean. It is calculated by taking the differences between each number in the data set and the mean, squaring the differences to make them positive, and then dividing the sum of the squares by the number of values in the data set....
