First of all you need a scientific calculator, one with sin cos, tan, log etc. If you do have one, look for a key marked **EE **(Texas Instruments) or **x10^x** (Casio) or **EXP (Casio, Sharp, Canon).**

To enter 5.10*10^(-7) ,

type in 5.10[EXP] (-)7 then ?nter, Exe, or =.

It is a frequency table where the entries are the relative frequencies

relative frequency= (frequency/sum of all frequencies). The frequency can be expressed as a decimal number or a percentage. In that last case, the total of all frequencies will be approximately 100% (due to rounding errors).

For a plane wave in a homogeneous medium, the phase velocity of the wave is related to the frequency and the wavelength by the relation

velocity = wave_length*frequency

In this case

velocity (in m/s)=(4*10^-3 m )*(3*10^9 s^-1)=12*10^(9-3)=12*10^6

Thus**velocity=1.2*10^7 m/s**

velocity = wave_length*frequency

In this case

velocity (in m/s)=(4*10^-3 m )*(3*10^9 s^-1)=12*10^(9-3)=12*10^6

Thus

To avoid mistakes due to faulty conversions, you must use SI units.

4 mm =4*10^-3 m

3 GHz=3* 10^9 Hz=3* 10^9 (s^-1)

Your result will be in**m/s**

4 mm =4*10^-3 m

3 GHz=3* 10^9 Hz=3* 10^9 (s^-1)

Your result will be in

Put the frequencies into the list LFREQ instead of L2.

In the context of statistics the relative frequency of a data item (for ungrouped data) or a class (for grouped data) is equal to the ratio of the frequency of the data item or class divided by the sum of frequencies of all the data items or classes multiplied by 100%.

If you want the probability not the relative frequency, do not multiply the ratio by 100%.

Example: In a sample with N data items, a particular items occurs n times. Its relative frequency is equal to (n/N)x100%

There is no such thing as turning the frequency on on the Casio calculators. Just enter your data in lists. Choose one List where you put the frequency information. When you want to GRAPH or perform CALCulations you have a TAB labeled SET corresponding to key F6:SET. When you press F6, a new screen open where you assign the list to the variables.

Here are a few screen captures to help you.

Press F2:CALC (or F1 Graph). The Tab SET appears at the bottom of screen

Press F6:SET

Higlight the line 1-Var Freq (or 2-Var Freq). The bottom of screen shows F1:1 and F2:LIST. If frequencies are not equal to 1, press F2:LIST to assign the frequency list. I entered 2.

List2 is now the frequency list.

Press EXE to perform stats.

See that n=19.

If you have a frequency list it must be entered in a statistical list, L2, L3, ...or L6.

If the frequency of all elements is 1 you do not need to enter the frequency in a list. When you go to draw the box plot, the frequency will be set to 1.

Hello,

I am afraid I do not understand. The frequency of a PARTICULAR score is the number of times that particular value occurs in the data. It is not the number of data.

Ex: the data are:

4, 6, 5, 4, 4, 8, 9, 3, 3, 6, 7

Frequency of (3) =2

Frequency of (4)= 3

Frequency of (5) =1

Frequency of (6)= 2

Frequency of (7)=1

Frequency of (8)=1

Frequency of (9)=1

Number of data =11 (n=11)

You compute the mean M

M= (2x3 + 3x4 +1x5 +2x6+1x7+1x8+1x9) /11 =5.363636..

As you can see, if a term is not repeated it is multiplied by 1 (its frequency is one). Value 3 occurs twice (hence 2x3); value 4 occurs 3 times (3x4), etc.

To calculate by hand the sum of squares

**3:** (3-5.3636)^2 + (3-5.3636)^2 .................... = **2x(3-5.3636)^2**

**4:** (4-5.3636)^2 + (4-5.3636)^2 +(4-5.3636)^2 = **3x(4-5.3636)^2**

**5:** (5-5.3636)^2 ...................................... .= **1x(5-5.3636)^2**

**6:** (6-5.3636)^2 +(6-5.3636)^2......................= **2x(6-5.3636)^2**

**7**: (7-5.3636)^2.......................................... .=**1x(7-5.3636)^2**

**8**: (8-5.3636)^2......................................... ..=**1x(8-5.3636)^2**

9: (9-5.3636)^2......................................... ..=**1x(9-5.3636)^2**

If I have not made a mistake the sum of squares is 40.5454

**Standard Deviation**

The standard formula above gives s= square root (40.5454/10) =2.01

** Population Standard Deviation**

The population Standard deviation above is S= square root (40.5454/11) =1.9198

So if you perform the calculation with the calculator the only times you need to enter the frequency is for repeated terms. When you have to enter 6 above, its frequency is 2 you proceed as follows

**6 [2nd][FRQ] 2 [Sigma+]**

Once you entered the raw scores, the calculator does the rest.

Hope it helps.

Here goes if you still need this...

STAT, EDIT, put information into L1 if only one variable stats, but put info into L1 and L2 if it is frequency table stats.

Then choose Stat, over to CALC, 1, enter...if 1 variable stats then press enter again. If frequency table stats, then choose STAT, over to CALC, 1, 2nd, 1 [L!], 2nd, 2 [L2], enter.
