This has saved me dozens of hours I would gave spent struggling and made me overall more productive. I'll be using the app through the next course in my math series. This App is so good! It does exactly what it should do, the Camera AI is good too, but for the situation if you can't use it, there's still a calculator.

Amazing app with on point recognition even with bad camera and faded screen, also offers steps for how to solve equation which is real helpful, helped me in 7th grade math a lot, i use it to 'reverse engineer'problems as that seems to help me understand the process better.

Russell Tam

All the problems you type or snap, there's always answer to it, ads at the bottom are annoying, i love how they give the option and how to do the problems in math, It's very helpful with homework, 10/10. The app is great, it does everything that is mentioned in the description plus more.

Find its standard deviation. Solution : Σf = N = 65 Σfd 2 = 556 (Σfd2/N) = (556/65) = 8.55 Σfd = 6 = Σfd/N = 6/65 = 0.09 σ = √ (8.55 - 0.09) ⋅ 5 σ = (√8.46) ⋅ 5 σ = (2.91) ⋅ 5 σ = 14.55 The standard deviation is approximately 14.6. Apart from the

In order to get the standard deviation, take the square root of the sample variance: √9801 = 99. How do you find the sample standard deviation of grouped data? The standard

Variance and standard deviation (grouped data)

For example, if you have the same four measurements of 6, 8, 12 and 14 and want to find the relative standard deviation, first find the mean and standard deviation, which are 10
