2. In this powerpoint presentation, the aim is to show ;
how to draw error bars by using logger pro (3.8)
how to add maximum and minimum lines (worst lines)
how to add different values of uncertainty for each measurement
PS: Point 2 and 3 are especially necessary for your physics classes.

3. adding error bars
First enter your datas and draw the best fit line that you want.

4. Then press on data set with double click and choose ‘options’ from the window that is opened.

7. If you want, you can add best fit line
If you want, you can add best fit line. (For this experiment , linear fit is suitable.)

8. adding maximum and minimum lines
First press “f(x), curve fit” button and choose “manuel fit type”.
Unfortunately, it should be done manuelly...
Enter ‘m(slope)’ and ‘b(y-intercept)’ values and then, try to fit these lines.

11. adding different uncertainty values for each measurement
First of all, draw your graph with techniques that you have already learnt by using logger pro.

12. Then, choose ‘Data’ section and ‘New Data Set’.

13. Enter your uncertainty values for each colomn to Data Set 2.

14. Then, go back to your original datas
Then, go back to your original datas. And click double on the title of colomn that you want.
A window called ‘Manuel Colomn Options’ comes and choose ‘Options’ section.
Tick ‘Error Calculations’ and ‘Use Colomn’ parts.

16. Let’s assume that you chose X column from data set 1 and you want to add its uncertainty values which are accessed to column X in data set 2.
You made a double click on title of column X in data set 1.
After ticking ‘use column’ part, choose ‘Data Set 2|X.

19. Now, let’s add the uncertainty values of Y column on data set 1 by using the techniques you learned.
You can use two different methods now. One is using ‘Error Constant’ part and the other one is by using ‘Use Column’ part.
