Tutoring statistics, you cover linear regression. The tutor shows how to get a best-fit line on the Casio fx-991ES PLUS C.<\/h1>\n

Let’s imagine you have the following data<\/p>\n\n\n\n\n\n\n
x<\/td>\ny<\/td>\n
10.1<\/td>\n14.2<\/td>\n<\/tr>\n
17.3<\/td>\n19.5<\/td>\n<\/tr>\n
25.4<\/td>\n22.9<\/td>\n<\/tr>\n
40.0<\/td>\n31.8<\/td>\n<\/tr>\n<\/table>\n

Furthermore, you’d like to find a line of the form y=A+Bx that fits the data. Here’s how you might do it using the Casio fx-991ES PLUS C:<\/p>\n

    \n
  1. Press Mode then 3 for Stat mode.<\/li>\n
  2. Press 2 for y=A+Bx<\/li>\n
  3. In the table that appears, enter the x and y values.<\/li>\n
  4. After all the x and y values have been entered, press AC.<\/li>\n
  5. Now, press Shift then 1.<\/li>\n
  6. Press 5<\/li>\n
  7. You’ll see choices for A, B, and other stats. Select the one you want, then press Enter.<\/li>\n
  8. If, for example, you select A first and get its value, press Shift then 1 then 5 to return to the other choices. You can then choose B.<\/li>\n<\/ol>\n
