How to Understand Measurement Uncertainty in TOF Mass Spectrometry and Ion Mobility-Mass Spectrometry
1. Understand the Measurement Scales Survey analysis is not possible without really understanding the scales. As we know, survey data can be divided intoqualitative and quantitative data. While qualitative data encompassesopen-ended questionsand does not require a numerical scale, quantitative questions ...
Example:Open-ended questions require customers to write detailed answers. Suppose you want to know what customers think of your website and their experience navigating it. Of course, you’d want a detailed account of each feature to understand the kind of customer experience you offer, but it’...
A quarterly or an annual measurement will only provide you with a snapshot of customer success. It won’t help you to measure the reaction to a new launch, or the integration of a new system. It also won’t help you to narrow down whether overall customer sentiment has changed, or whet...
Each scale can have its variations depending on the measurement sensitivity you require from the customer.For example:A 7-point Likert scale is more sensitive than a 5-point scale as it provides more options for customers to represent the level of effort they expend to get their issues ...
advocates. Conversely, they really don't like spending time and effort on activities they don't agree with. Don't be intimidated by their questions; if they're pressing you, it's likely because they're trying to get on board by making sure they agree with and understand what ...
[Note: All in all, the differences in stated length and measured length via a straight-tape measurement are typically within 1-3 cm, which is quite small; the other sections here are typically much more important to consider when thinking about how long various skis feel on snow. But, it...
To understand how interference fringes form on film, you need to know a little bit about light. Light is part of the electromagnetic spectrum — it's made of high-frequency electrical and magnetic waves. These waves are fairly complex, but you can imagine them as similar to waves on water...
To find the scale factor, you first decide which direction you are scaling: Scale Up (smaller to larger) = larger measurement / smaller measurement Scale Down (larger to smaller) = smaller measurement / larger measurement The scale factor for scaling up is a ratio greater than 1. ...
but the end user still doesn’t know the temperature measurement metric or unit of measure. We want to be able to say, “hey, here's an experience that says these are the entities and attributes and relationships that you as business users or a regular users unde...
