There are many benefits to using folders when working with lots of files. Here are a few examples:
- You can use folders to sort your files by type, almost like drawers in a desk, so you might have folders for Music, Photographs, Documents, etc.
- You can use folders to group files together into a specific group. For example in your Photographs folder you might have a folder titled BirthdayPhotographs for all the photographs from your birthday.
- As in the example above you can nest folders to create sub-categories. Documents might include folders for Homework, Stories, Poems
- Folders can have different permissions applied to them, allowing you to keep personal files in a private folder only you can access, or secret files in a folder that doesn't show up in the normal list of folders!
Answer:
d. cross-sectional study
Explanation:
In research, a cross-sectional study consists of a gathering of data from a population or a subset of the population we want to investigate at an specific point of time. In other words, the data will give us an idea of what's happening within a group in a particular moment in time.
In this example, the researcher gives 20-year-olds, 40-year-olds, and 60-year-olds a questionnaire. He wants to know if older people are calmer than younger ones. We can see that <u>he wants to know what's happening within this groups (the 20 year-olds, the 40's and the 60's) during this particular time of their life </u>and therefore determine if the 60 year-olds are calmer. Therefore this is an example of cross-sectional study.
Vision test is the gold standard test for assessing visual function and how it responds to <u>light stimuli</u> that enter the eye and produce a sensation of light and possibly color as well.
<h3>What is a vision test?</h3>
It is a test used to determine the ability of our visual system to distinguish details clearly at a given distance and under certain conditions.
The deeper retina contains the receptors for light stimuli (photoreceptors), these tests measure the eye's ability to define details and are established as a mathematical relationship between the size of an object and the distance it is from the eye.
Therefore, we can conclude that a vision test is the gold standard test for assessing visual function and how it responds to <u>light stimuli</u> that enter the eye and produce a sensation of light and possibly color as well.
