The tutor shows how to get a best-fit line with the HP-10B.<\/h1>\n

Imagine the following data:<\/p>\n\n\n\n\n\n\n
x<\/td>\ny<\/td>\n<\/tr>\n
3<\/td>\n10.1<\/td>\n<\/tr>\n
4<\/td>\n14.7<\/td>\n<\/tr>\n
9<\/td>\n32.5<\/td>\n<\/tr>\n
12<\/td>\n47.1<\/td>\n<\/tr>\n<\/table>\n

<\/p>\n

To get a best-fit line for it of form y=mx+b, here are the steps:<\/p>\n

    \n
  1. \nFirst, clear the stat registers of the HP-10B by pressing _<\/span> \u2192M.<\/li>\n
  2. Key 3, then INPUT, then 10.1, then \u03a3+.<\/li>\n
  3. Key in the other data pairs similarly.<\/li>\n
  4. In y=mx+b, you get b by pressing 0 _<\/span> 5.<\/li>\n
  5. Now, get m by pressing _<\/span> K.<\/li>\n<\/ol>\n

    For this example, b=-1.9, while m=4. The best-fit line is y=4x-1.9<\/p>\n
