HOW DO YOU ADD UP TH FINAL MARKS?


It depends on your jurisdiction. In Ontario, the term mark has a weighting of 70, while the summative and final exams have a combined weighting of 30.

To illustrate, let's do an example.

Term mark worth 70% of final grade - 70
Summative mark worth 10% of final grade - 80
Formal exam mark worth 20% of final grade - 90

Your overall final mark would be as follows

70 x 0.70 = 49
80 x 0.10 = 8
90 x 0.20 = 18
------
Overall Mark 75

Good luck,

Paul

How many combinations of 56 cents are there?


Great question.

You could start with the number of quarters, which can be 0, 1, or 2.
If there are 0 quarters, then you only have dimes, nickels, and pennies to worry about. You can have 0 to 5 dimes. There can be 0 to 11 nickels. For pennies, there can be 1, 6, 11, 16, 21, 26, 31, 36, 41, 46, 51 and 56.

Time to work out lots of combinations!

Sounds like a summative project for a data management or statistics course or a great computer programming assignment;)

Good luck,

Paul

Find summation(x-xbar)^2, given that summation x =160 and n=10 whre there are no data points given?


You need one more piece of information, either the standard deviation, the variance, or the sum of squares. With only the two pieces you give, there are an infinite number of solutions.

Notation summation


Since x^y doesn't depend on i, the sum is simply n*(x^y).

There are 1 to n terms, each of which is x^y.

I can't use an imaginary number in a sigma notation


The summation function only works in the real mode, not the complex mode. You'll find that the same limitation applies to many other functions, such as the integration.

See page E-42 of this manual for the functions that are allowable in complex mode.

I am trying to find the variance can this be found with the TI-30X II S I have the Texas Instruments TI-30 X II S on solar batteries, it has 2nd function but i am not sure how to find the summation for...


There is a quick guide here which should help http://education.ti.com/downloads/guidebooks/scientific/30xii/30xiiqrg-eng.pdf
So you press 2nd Function , select 1-Var or 2-Var (for paired datat) then enter your data pressing down arrow after each and Enter to finish then press STAT / VAR to see the various variables

Please give me a thumbs up if this helped

What is a proses summation


There isn't any such thing.

If you mean "process summation" or "process of summation" then it can refer to any number of things in mathematics. If you mean something else, then I can't guess.

How do you enter frequencies for finding standard deviation? For example, Frequency=50, total of X or raw scores = 366.5. Summation of X squared =2836.39. What is standard deviation? How do you enter the...


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
sd.jpg
The standard formula above gives s= square root (40.5454/10) =2.01
Population Standard Deviation
popsd.jpg
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.
