Great video. My textbook uses the same example you show. I have to admit that instructional videos like this one make it much easier for me to understand the concepts, compared to what a face to face lecture can provide (noisy students, less than optimal viewing point, limited time for lecturing, and the inability to rewind the instructor as many times as you need).
amazing explanation, thank you so much. I will watch the video again and practice. Sir, I have a question, in a case that the quarters are in different amounts of money ($50, $30, $60.....$10) and they don't follow any order as in your example (1,2,3...13,14) how can we know the value of X to use it in the formula Y= a+bX?. Thanks in advance
Here we arrived at an Equation Y=441.77+359.6X,,,, let's try for X=10,as per our existing data we must get Y=4500. But Y value comes lesser than this...Means we must include some error value...Please clarify??????????????
