You won't get the question finished in the time allotted compared to a student that knows how to do it with the calculator. <br /><br />Russellhttps://www.blogger.com/profile/02342230372505375612noreply@blogger.comtag:blogger.com,1999:blog-2961727131900697758.post-44028930667276149932012-09-07T20:47:07.397+08:002012-09-07T20:47:07.397+08:00Just do it by handJust do it by handAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2961727131900697758.post-39270153425822641142010-09-27T19:21:17.520+08:002010-09-27T19:21:17.520+08:00I haven't seen it yet.. the old fx MAV program...I haven't seen it yet.. the old fx MAV programme was very good for solving MAV problems. Another teacher at our school says he ported them across easily last year, but we've never been able to find out where or how it did it.Russellhttps://www.blogger.com/profile/02342230372505375612noreply@blogger.comtag:blogger.com,1999:blog-2961727131900697758.post-71350198968973162412010-09-11T16:34:21.813+08:002010-09-11T16:34:21.813+08:00There is supposably a MAV program for the classpad...There is supposably a MAV program for the classpads does anyone no where i can get it? my maths teacher said he got his from the casio website but i cant seem to find it on there any help?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2961727131900697758.post-27912815039096617602009-08-26T19:51:45.168+08:002009-08-26T19:51:45.168+08:00I did consider this and even looked at Mat->lis...I did consider this and even looked at Mat->list and list->mat functions to copy the data across and back.<br /><br />I did do the exercise with spreadsheet mode with my students today and they did seem to get it, combining it with CMA (as this allowed to go back to single units per line and generate a regression line) and residuals seem to work ok, as long as they had a firm understanding of what the intention of the Saddler exercises were.<br /><br />I used an icecream shop to look at how residuals could be used to predict ice cream requirements and the linear regression equation found in spreadsheet mode could be manually entered under graph and tab mode.<br /><br />I suppose I was just disappointed that it actually got harder going from the fx to the CAS calculator and that it required manual entry in stats mode to do some fairly simple. I suppose I should get out the programming manual and code something up, but I imagine it's around the corner anyway.Russellnoreply@blogger.comtag:blogger.com,1999:blog-2961727131900697758.post-32161077455960861652009-08-26T19:04:18.160+08:002009-08-26T19:04:18.160+08:00A different method for dealing with moving average...A different method for dealing with moving averages on the Casio classpad is to input the collected data (Ie. time and moving averages) into separate columns in the 'statistics' section of the CAS calculator. To the best of my knowledge, moving averages would have to be calculated by hand, but after reading your post I think this is an easier process, especially in regards to graphing.<br /><br />To graph your data in statistics mode, under 'calc' click on 'linear regression' (or whichever is appropriate). A small screen will appear with the equation of the line of regression as well as the correlation coefficient before graphing the data with the line of regression already in place. You can interpolate and extrapolate the data easily (under analysis -> trace) if you have the right domain. Zoom out of the graph to extrapolate data.<br /><br />This is just an alternative method in handling moving averages.Anonymousnoreply@blogger.com
