your score is above average, but if you really want to know where you are on the "curve," you should calculate your Z-score. This important statistics tool not only takes into account the average of all the test scores but also the variation in the results. To find the Z-score, you ...

Standard score is a statistics term. The standard score shows how far away from the mean a score falls. It is also known as a z-score. Using a z-score table, you can find where the score falls on the table and figure out what percentile the score falls in. This is a way of sta...
Step 1:To calculate the z-score for a single data pointx, we must first identify two additional values: The mean,μ, of the distribution from which the data point was sampled The standard deviation,σ, of this same distribution Step 2:Apply the z-score formula:z=x−μσ ...
You calculate a standardized value (a z-score), using the above formula. The symbols are: X: theobservation(a specific value that you are calculating the z-score for). Mu(μ): themean. Sigma(σ): thestandard deviation. These values are always given in the question. ...
How to Calculate a Z-Score in Statistics Find the area to the right of a z score. Using the Normal Approximation to solve a Binomial Problem What is the continuity correction factor? Area Under a Normal Distribution Curve Index Central Limit Theorem. ...
The standard score (more commonly referred to as a z-score) is a very useful statistic because it (a) allows us to calculate the probability of a score occurring within our normal distribution and (b) enables us to compare two scores that are from different normal distributions. The ...
How to calculate mean? The answer to this question is very easy in Maths. Mean is nothing but the average of a given set of data or values. Find the mean with examples, at BYJU’S.
1. To calculate Z-scores, firstly go to theDescriptivesby going toAnalyze > Descriptive Statistics > Descriptives... 2. Next, move the scores that need to be converted into theVariable(s)box to the right. Also, click the option toSave standardized values as variables. It is this simple...
Be sure to usesignificant figureswhen rounding your final answer. A Worked Example Suppose you're given the data set 1, 2, 2, 4, 6. Work through each of the steps to find the standard deviation. Calculate the mean of your data set. The mean of the data is (1+2+2+4+6)/5 = ...
