Can you please read the math in this image for me?

[BeautifulMind59]

can you please read the three formulas? I know how to solve them, but just on paper. I have a presentation tomorrow and I have no idea how to read and pronounce a formula.

For example this formula: E=mc^2 reads: e equals m c squared.

+1 y

Thank you!

The first one to me would be as follows:

The mean squared error is equal to one over n multiplied by the sum of the data points minus the mean of those points, squared.

The second one:

The NRMSD is equal to the square root of the MSD divided by the mean of the data points.

Top: Mean squared error = the sum of the squares of (y sub i minus y hat sub i) divided by the number of samples
Middle: Normalized... = the square root of the mean squared error divided by the mean
