English term or phrase: Standardisd or normalised
What is the difference, if any, between these two?

Do I standardise to a value or normalise?

Translated originally from "normalizado" in a ES tec report.

Thanks for your opinions ;)

Explanation:
Normalised was already suggested, but I wanted to offer a more detailed explanation, as it seems that there is a misconception about "correcting fluctuations", which is not the case.

This text is talking about a mathematical/statistical process called normalization. This is basically a method to take a set of data in a certain range into another range. A linear normalization does not change the value distribution in the range. (In other words, it does not modify the fluctuations, only their amplitude.) Imagine a white knit scarf that is 1m long with stripes at every 10 cm. Now, you stretch this scarf to 2m, and you will have the stripes at every 20 cm. Next, you put this wool scarf into the washing machine, and guess what, it shrinks to 50 cm. You have your stripes at every 5 cm.
Now, if your 1m long scarf originally had 10 stripes at 5 cm intervals, then 2 more stripes at 25 cm intervals, this distribution would not change after stretching/shrinking the scarf. The 2 m long stretched scarf would have 10 stripes at 10 cm intervals, and 2 more stripes at 50 cm intervals. The shrunken 50 cm scarf would have 10 stripes at 2.5 cm intervals, then 2 more stripes at 12.5 cm intervals. So, we did not "correct the fluctuations".
I hope this example is easy to understand.

So, here, what happens is that the datapoints (I am not sure if they are values of energy, voltage, current, or what) are in a range, probably in the zero (minimum) and 100% (maximum) range. They want to scale the values into the 0-60% range, perhaps to make some phenomena more visible (such as the slope of some change, etc.) or to compare data from measurements taken in different ranges with each other. Scaling from a 0-100 range into the 0-60 range would involve a simple division by 60.

Alternatively, they may be actually modifying the physical values and forcing them into the 0-60% range.

Here is an English text that contains the same phrasing:
"The SPT Analyzer measures the energy transferred into an instrumented SPT rod. This permits the adjustment of the measured N-value to the normalized N60 for standard 60% energy transfer into the rods."

In the PPT presentation at the first link below, there is an explanation about the mathematics used for normalization.

The second link below has a figure (Fig 6) that shows two sets of data in different ranges, and then the normalized resluts as well. You can see it is much easier to compare those graphs when they are all normalized.

both depending on context


Explanation:
According to the Spanish dictionary, the word "normalizado" has two meanings, namely, 1) to normalize and 2) to standardize, so I you're lost at which to select.

But I think both could be used, according to the context, but since there is almost no context in your above question, I cannot say which is correct. Standardizing a value could mean making or setting a certain value to a industry standard, and normalizing value could mean correcting a value which has fluctuated to the normal value.

Asker: Hi, thanks for that. The problem is that my total context is as follows: N60 = Corrected value standardised/normalised to 60% of the energy (and here N is for number i.e. 60) Does that help any better? Thanks, Chris.

Asker: Thanks for all your help :)

Explanation:
2N60 = Corrected value standardised/normalised to 60% of the energy (and here N is for number i.e. 60)"
The clue is in the word corrected.
The OED defines normalise as "Make normal or regular, cause to conform. In this case the word corrected shows that action has take on the value to make it conform.
Standardise would imply that it had simply been set at that value.
