The calculator then asks SCI 0~9? Thisgives the option of how many digits are displayed. The gives you 10 digits. Notice asmall sci appears in the screen.If you press ×1004whichmeans3.570 × 104. This rounds the number to 4 digits.Practise using the and keys on your calculator8.Factorial x!Look at your calculator and find the key with the symbol x! on it. You will come across this symbol when doing the Binomial Distribution. This is called the factorial key.3! means 3 × 2 × 1 and 5! = 5 × 4 × 3 × 2 × 13! = 65! = 120How many ways would you guess that we could arrange ten people?That is, how large would you estimate 10! to be? Use your calculator to find 10!You should get 3 628 800.10! = 10 × 9 × 8 × ... × 3 × 2 × 1(Thank goodness this can be done on the calculator.)Factorial ruleThe number of ways of arranging n items in order is known as ‘factorial n’ which is symbolised as n! where:n! = n× (n – 1) × (n – 2) × ... × 3 × 2 × 1ing memoryTo calculate the following it may be useful to use the memory key for each term:Example:To make sure memory is clear, first pressorand make sure you are in normal calculation mode [may need to press mode 1].An M appears in the display when you put something in memory.916–()216---------------------2316–()216------------------------1716–()216------------------------++key to activate M–)To do the calculation above, press the following keys- this puts the first term (3.0625) into the memory then press- this adds the second term (3.0625) into memory then press- this adds the third term 0.0625 to memory.To find the answer press The answer should be 6.1875.Example 2calculate the following:firstpress the following keys:your answer should be 11.39917438(There are other memory keys in your calculator – the A to F keys, accessed by using SHIFTSTO and RCL – try them yourselves.)1817---------1717---------1217---------++10.Statistics10.1 Mean and standard deviation – single dataThe formula for the mean is The formulas for the sample standard deviation are(sample)(population)Your calculator will calculate the mean and standard deviation for you (the populationstandard deviation or the sample standard deviation – in data calculations you will usually use the sample standard deviation.)On the Casio fx -82MS , σ and s are found in s-V AR. The positions of keys needed are shown on the diagram below.x Σxn-----=σn σn -1input data keyTo find the mean and standard deviation,firstly you must access the statistics mode of the calculator by using the keysfollowed bySD will appear in the centre of the screen.Note that once you are in the statistics mode, the keys shown within the blue lines are active.There are 3 such keys on the Casio fx -82MS. Make sure you can locate them. Before starting any computations always clear the statistic’s memories using Scl. PressI will use the data set A (–5, 2, 3, 4, 11) to demonstrate the use of the calculator. Note that I have shown the use of thekey where necessary.Step 1: Input the e theThe display should read n = 5. (This means 5 observations have been input).Step 3: Display the mean and standard deviation.Pressthe display shows three alternativesPressx σn = 5.099019514Pressx σn –1 = 5.700877126ExampleUse your calculator to find the mean, standard deviation and variance for data set B: –18, 1, 3, 9, 20.(the variance is the square of the standard deviation)__________________________________________________________________________After you are in the statistics mode and cleared the statistics memories, the keystrokes required are:The mean is 3, the standard deviation is 13.87 and the variance is 192.5. button accesses a number of extra statistical functions.If you have made an error with inputting your data you can correct it by using the up and down key.For example, you inputreads x 3 = 60, then pressIn the example below, the progressive calculations are shown simply to give you someunderstanding of the underlying processes – you should do one or two examples in detail and then check them by calculator.=Σx 2 =815=Σx = 15=n= 510.2 Mean and standard deviation of frequency distributionGiven below is the frequency table for the weights (kg) of a random sample of 30 first year university female students. Find the standard deviation, the variance and the mean.The calculations needed to obtain the standard deviation without statistical keys for these data are:Σx 2 = 602 × 2 + 612 × 14 + 622 × 8 + 632 + 642 × 5 = 114 495Σx = 60 × 2 + 61 × 14 + 62 × 8 + 63 + 64 × 5 = 1 853s = = Thus:s= 1.2 kg and s 2 = 1.4 kg 2= Note: In calculations like the above you should carry as many decimals as possible until thefinal result. The number of decimals to be retained at the end depends on the accuracy of the data values – one rule of thumb is to have one more decimal than in the original data.Notice how the frequencies were used in the above calculation.The calculator usage now has a small modification because we have been given the frequencies for the variable values. (There is no need to input each single observation.)Graduate’s weight(kg)FrequencyCumulative frequency6022611416628246312564530Σx i 2Σx i ()2n ⁄–n 1–--------------------------------------114 495 1 853()230⁄–29-------------------------------------------------------114 495114 453.6333–29--------------------------------------------------------- 1.4264==Σx n -----185330-----------61.8 kg==The keystrokes required are:The display should read n = 30.Thus, as expecteds = 1.2 kg, s 2 = 1.4 kg 2 and = 61.8 kg Exercise 6Find the mean, standard deviation and variance of (a)The annual rainfall data for the years 1971 – 1990Year 1971197219731974197519761977197819791980Rain (mm) 1 3409901 1201 7362601 1001 3791 1251 4301 446Year 1981198219831984198519861987198819891990Rain (mm)1 4591 6781 3459781 0021 1101 5461 6721 4671 123x(b)The sample of snail foot lengthsAnswers:(a)Rainfall statisticsmean:µ = 1 265.3 mm standard deviation:= 336.4 mm variance:σ2 = 113141.7 mm2 (b)Snail statistics mean:standard deviation:s = 0.70 cm variance:s2 = 0.49 cm2Snail foot length (cm)2.2 4.13.54.5 3.2 3.7 3.0 2.63.4 1.6 3.1 3.3 3.8 3.14.7 3.72.5 4.33.4 3.6 2.9 3.3 3.9 3.13.3 3.1 3.74.4 3.2 4.1 1.9 3.44.7 3.8 3.2 2.6 3.9 3.0 4.2 3.5σn-111.Linear regressionTo access the linear regression mode you presskey once followed bythen a small REG appearsExampleSuppose we had a sample of 10 of the same type of banana. Their lengths and skin thicknesses were measured.

计算器按键的使用说明

计算器按键的使用说明.1、电源开关键：ON、OFF2、输入键：0—9、. +/—：正负转换键3、运算功能键：+ - * / (注意:加、减、乘、除键在计算时都可能代替等号键) √：开平方键，用来进行开平方运算。

先输入数字，再按下此键，不必按等号键即可得出结果。

4、等号键：＝5、清除键：①C：清除键。

在数字输入期间,第一次按下此键将清除除存储器内容外的所有数值.如果是太阳能计算器，在计算器关闭状态下，按此键则开启电源，显示屏显示出“0”。

②AC或CA键：全部清除键，也叫总清除键，作用是将显示屏所显示的数字全部清除。

③→：右移键。

其功能是荧屏值向右位移，删除最右边的尾数。

④CE：部分清除键，也叫更正键。

其功能是清除当前输入的数字，而不是清除以前输入的数。

如刚输入的数字有误，立即按此键可清除，待输入正确的数字后，原运算继续进行。

如5+13，这时发现“13”输入错了，则按“CE”键就可以清除刚才的“13”，但还保留“5”这个数。

值得注意的是，在输入数字后，按“+”、“-”、“/”、“*”键的，再按“CE”键，数字不能清除。

⑤MC：累计清除键，也叫记忆式清除键。

其功能是清除储存数据，清除存储器内容，只清除存储器中的数字，内存数据清除，而不是清除显示器上的数字。

6、累计显示键：（1）M+：记忆加法键，也叫累加键。

是计算结果并加上已经储存的数；用作记忆功能，它可以连续追加，把目前显示的值放在存储器中（也就是将显示的数字与内存中已有的任何数字相加，结果存入存储器，但不显示这些数字的和）。

如去和小商贩买几种冰淇凌，买5筒五羊牌雪糕，每筒1.6元；买10筒绿色心情，每筒0.8元；买15筒蒙牛布丁，每筒0.4元。

共多少元？如先输入“5×1.6”→按“M+”键（把“5×1.6”的结果计算出来并储存起来）→然后输入“10×0.8”→按“M+”键（把“10×0.8”的结果计算出来并和前面储存的数相加）→接着输入“15×0.4”→按“M+”键（把“15×0.4”的结果计算出来并和前面储存的数相加）→最后按“MR”键（把储存的数全部取出来）→则出结果“22”（2）M-：记忆减法键，也叫累减键。
