Question about Sharp EL-520WBBK Calculator
Can you explain how to do linear regression with the Sharp EL-520W calculator?
SOURCE: how to calculate
It's very simple: the calculators have a default base 10 so that log x it's log x base 10 so here is some logs:
log x base y = log x / log y
log (x*y) = log x + log y
log (x/y) = log x - log y
Hope it's helped

I am aware that the solution provided below is valid for the CFX/FX-9850G/GB/ but I will supply it. I remain convinced it will help you for your calculator.
In the main menu select [STAT] icon to enter Stat mode and display the statistical data lists. Use the satistical data lists to input data and perform statistical calculations. Use the arrows to move the highlighting around the lists.
Exemple: Enter the following values in List 1
1st line enter 90 [EXE]
2nd line 85 [EXE]
3 79 [EXE]
4 75 [EXE]
5 70 [EXE]
6 68 [EXE]
7 56 [EXE]
When finished you press [F2:Calc], then [F1:1Var] and the statistical results appear on screen.
Title of screen : 1-Variable
x bar =74.7142857
Capital Sigma x= 523
Capita Sigma X squared = 39851
x lower case sigma n = 10.5249945
x lower case sigma n-1= 11.3682934
n = 7
Scroll down with Down arrow to access other data
Xbar -x lower case sigma n =64.1892911
x bar + x lower case sigma n = 85.2392802
All you have to do now, is to look at the theory you learned and interpret what these values mean.
Hope it helps.
