Sharp EL—5002(大连DS—5,广州8031)型,属于可编程序式电子计算器,可进行简单的程序输入和记忆,基本可满足田间试验,畜牧试验的统计和分析。此型号功能比较广泛,本文介绍程序编制在生物统计上的应用。该机型有记忆能力,可以输入39步(一键一步)计算程序。定侧键LRN(程序记忆键),将编制好的程序输入进去,让计算器进行学习记忆(通过变数指定键[x],输入任意数),然后定侧键在COMP(程序启动键),就可进行变数计算。一、回归方程计算已知y=3+1.456x,试求x为2,5,7,9,11时的y值。
Sharp EL-5002 (Dalian DS-5, Guangzhou 8031) type, is a programmable electronic calculator, can be a simple program input and memory, the basic field test to meet the statistics and analysis of animal husbandry test. This model features a more extensive, this article describes the application of programming in biostatistics. The model has a memory capacity, you can enter 39 steps (one key step) calculation program. Set the side key LRN (program memory key), enter the programmed program, and let the calculator learn and memorize (enter any number through the variable specified key [x]), and then set the side key to COMP (program start key) Can be variable calculation. First, the regression equation calculation Known y = 3 + 1.456x, try x is 2,5,7,9,11 y value.
