Question about Texas Instruments BA-II Plus Calculator

1 Answer

Standard Deviation & Mean ( With Probability)

Consider this example:

Asset G:

[Probability] [Return]
0.4 0.35
0.3 0.1
0.3 -0.2

Is there a way me to enter the data above and get it to tell me the:
1) Expected return (Answer = 0.11)
2) Standard Deviation (Answer = 0.2278)

I have used the [Data] mode but this seems only suitable for one set of data.

    The solution is not working.. not the website nor the Youtube Vid,

    Please I need an answer to the same question..
    - We can get the expected return from the (EXy) => Summation of XY where x is the return and y is the probability (Risk)
    -But we can't get the Standard deviation of returns (Segma) => NOT segma X NOR segma Y

    Please we need the solution swiftly.. it's important for the exam :)
    saving us alot of time and effort

    Hi Mo

    The old links to calculator and YT video is no longer valid

    If you wish to compute expected return and standard deviation from a set of data with possible returns and probabilities of occurence, then please follow this linkhttp://finance.thinkanddone.com/online-e... to an online calculator that calculates expected return and standard deviation

How can I find the mean absolute deviation?


Mean absolute deviation.
Let's break it down into its components.
Mean - Average
Absolute - absolute value - sign doesn't matter - if negative, make positive
Deviation - difference from the mean

Let's do an example. Population 3 7 4 2. Total 16. Mean (Average) 16/4 = 4.

Deviations
3 - 4 = -1 absolute value 1
7 - 4 = 3
4 - 4 = 0
2 - 4 = -2 absolute value 2

Sum of these deviations 1 + 3 + 0 + 2 = 6
Mean (average) of these deviations is 6 / 4 = 1.5.

Good luck,

Paul

How do you find themean absolute deviation?


The mean is the arithmetic average, so add up all the numbers and divide by the number of numbers.

The standard deviation is a little more involved. The formula and example are explained here:

What is deviation standard


The standard deviation is a measure of how "tight" the samples are distributed around your mean.
In layman's terms, a small standard deviation indicates that most of your measurements are in the vicinity of the means; a large standard deviation corresponds to readings that are all over the place.
You could also say that the smaller the SD, the more your mean is representative of the data set.
For a better explanation, just look up Standard deviation on Wikipedia!

How do I calculate z score on TI-36X Pro?


To convert an x value to a z-score, the formula is:
(x value - mean)/standard deviation

Example: We have a number of height measurements that have a mean of 65.25 and a standard deviation of 2.84. One value is 68.5. To convert it to a z-score: (68.5-65.25)/2.84 = 1.144

Hope this helps!

About the formula in z-score


  • The formula for calculating a z-score (or standard score) is:
    z = (x - μ) / σ
  • The variables in the z-score formula are:
    z = z-score
    x = raw score or observation to be standardized
    μ = mean of the population
    σ = standard deviation of the population
  • Example of a z-score calculation:
    You have an observation of 14.75, a population mean of 12.2, and a standard deviation of 1.75. Therefore, the z-score would be:
    z = (14.75 - 12.2) / 1.75
    z-score = 1.46

How do I use the standard deviation function?


  1. Calculator must be in SD mode (standard deviation mode) :Press [MODE] [.]
  2. However, if [FIX] or [SCI] appears on display you must press [MODE][9] first.
  3. Data input always starts with [SHIFT][SAC], to clear the registers of old data.
  4. Type a number and press the [DATA] key, it is the [M+] key at the bottom right of keypad.
After you finish entering the data

Press [SHIFT] [9] (sigma n-1) to get sample standard deviation
Press [SHIFT][8] (sigma n] for the population standard deviation
Press [SHIFT] [7] (xbar) for the mean
Press [SHIFT] [6] (n) for the number of data entries
Press [SHIFT] [5] (capital sigma x) for the sum of values
Press [SHIFT] [4] (capital sigma x to y) for the sum of squares of the values

For additional information you might consider taking a look at the calculator manual.
