What is standardization: Definition and 11 Discussions
Standardization or standardisation is the process of implementing and developing technical standards based on the consensus of different parties that include firms, users, interest groups, standards organizations and governments. Standardization can help maximize compatibility, interoperability, safety, repeatability, or quality. It can also facilitate a normalization of formerly custom processes. In social sciences, including economics, the idea of standardization is close to the solution for a coordination problem, a situation in which all parties can realize mutual gains, but only by making mutually consistent decisions.
Dear PF Forum,
It's been a while since I logged in here. And I really do appreciate all the answers that I've been getting here.
Now, I wonder. Is there any standardization for 1 light year distance?
Is it 10 trillion kilometers, or
299,792,458 * 60 * 60 * 24 * 365.256 = ...
Hello everyone,
When working with variables in a data set to find the appropriate statistical model (linear, nonlinear regression, etc.), the variables can have different range, standard deviation, mean, etc.
Should all the input variables be always standardized and scaled before the analysis...
I'm learning basic probability and have some understanding of PDF's and CDF's now. (I've not done expected values yet though so I'm not familiar with that notation).
I've come across standardization of a random variable, X, which then gives a new random variable Y with the properties that Y has...
Let X be random variable and X~N(u,σ^2)
Thus, normal distribution of x is
f(x) = (1/σ*sqrt(2π))(e^(-(x-u)^2)/(2σ^2)))
If we want to standardize x, we let z=(x-u)/σ
Then the normal distribution of z becomes
z(x) = (1/σ*sqrt(2π))(e^(-(x^2)/(2))
and we usually write Z~N(0,1)
But as you can see...
Homework Statement
How do I figure out the concentration of Thiosulfate in mol/L or g/L if I am only given the following:
0.00167M Iodate (IO3-)
10g of 0.00167M Iodate (IO3-) in Solution
0.71266g of Thiosulfate necessary to titrate
IO3- MW = 174.9027 g/mol
Thiosulfate MW = 248.18 g/molHomework...
Hi, I have a problem concerning MRI image normalization and scaling data between 0 and 1.
I have three tissue classes with different intensity range on a set of images (intensity range for each tissue is varying from image to image): for one image for instance I have: GM (100-150), L(0-150)...
Homework Statement
Potassium permanganate (KMnO4) is used to determine the actual concentration of standard solutions containing the nitrite ion. The permanganate ion reacts with nitrous acid according to the following reaction.
2 MnO4- + 5 HNO2 + 5 H+ = 2Mn2+ + 5 NO3- + 3 H2O
Pipet in order...

It looks like Fortran 2008 is going through its final steps of standardization. What does this mean for scientific computing? Since people still use Fortran 90 despite new revisions up to 2003, will this go under the radar, or will this be a new and useful...
Substrate concentration (mg/cm^3) of influent to a reactor is normally distributed with \mu = 0.30 and \sigma = .06
The question is how would you characterize the largest 5% of all concentration values?
What does this mean?
It requires 46.5 mL of 0.215M NaOH to neutralize 15.0 mL of aqueous H2SO4. What was the molarity (M) of the acid sample?
I'm not quite sure how to approach this quesiton, if anyone has and starter tips please let me know.
Standardization of H2O2 Solution
H2O2 (aq) + 2 I-(aq) + 2H+(aq)------> I2 (aq) + 2 H2O(l)
2 S2O32-(aq) + I2 (aq) à 2 I-(aq) + S4O62-(aq)
i want to know
1.why the volume of S2O32- used in trial 2 is more than trial 1?
2.What is the use of Na2S2O3 (aq) in Part I?
