Hi I'm Sujoy. And in this series of tutorials I'm telling you about Curve Fitting. This is my fifth video in the series.And today you'll learn next how to do curve fitting directly on Casio fx-991ES scientific calculator,very easily. How to find the regression line without doing any calculation or graphing any graph/plot.
Topics explained in this video-
1. Types of linear equations representation - comparison
2. How to interpret x,y data set
3. How to enter data set into Casio fx-991ES calculator in mode 3 STAT or statistics mode (two variable statistics)
4. How to find values of x and y using the calculator (A or B)
5. Evaluating the equation of the line y=ax+b or y=A+Bx ( by two different methods)
6. What is correlation coefficient (r) and how to find value of correlation coefficient using Casio fx-991ES scientific calculator
7. Example question with graph
8. How to find value of y for given value of x and
How to find value of x for given value of y on the scientific calculator
That's it! How was the video? Let me know.
I've uploaded videos on Statistics,Numerical Methods,
Business & Financial Mathematics,Operations Research,Computer Science,Electrical Engineering,Android Application Reviews,India Travel & Tourism,Street Foods,Life Hacks and many other topics.
And a series of videos showing how to use your scientific calculators Casio fx-991ES & fx-82MS to do maths easily.
