can someone please help me understand how to get a z score. For example I have to find the z score for: x and y and x is 2 and y is 3

The Z score is the raw score in terms of standard deviations away from the mean. What are your mean and SD values?

Z = (score-mean)/SD

Certainly! To find the z-score for a given value, you need to know the mean and standard deviation of the dataset. Here's how to calculate the z-score step by step:

1. Calculate the mean (μ) and standard deviation (σ) of your dataset. If you already have them, proceed to the next step. Otherwise, find the mean by summing up all the values in your dataset and dividing it by the number of values. To find the standard deviation, subtract the mean from each value, square the result, sum up all the squared differences, divide by the number of values, and take the square root of the result.

2. Once you have the mean and standard deviation, you can calculate the z-score using the formula:
z = (x - μ) / σ

x represents the value you want to calculate the z-score for, μ is the mean, and σ is the standard deviation.

3. Plug in the values into the formula for both x and y.
For x:
z_x = (x - μ) / σ
z_x = (2 - μ) / σ

For y:
z_y = (y - μ) / σ
z_y = (3 - μ) / σ

Note: The z-score represents the number of standard deviations a particular value is away from the mean. It allows you to compare values from different datasets on a standardized scale.

To calculate the specific z-scores for x = 2 and y = 3, you would need to know the corresponding mean and standard deviation for those datasets. Once you have those values, you can substitute them into the formulas above to find the z-scores.
