Spectrum bias

Remember how you learned about the colors of the rainbow? There's red, orange, yellow, green, blue, indigo, and violet. But did you know that sometimes there are colors in between each of these colors? These colors are called shades or hues.

Now, let's think about a doctor who is trying to diagnose a sick patient. The doctor might use a test to help figure out what's wrong with the patient. But sometimes, the test can only see certain shades of the sickness. Just like the colors of the rainbow, there might be shades in between that the test can't pick up.

This means that the test might not be able to pick up all the different types of sicknesses that a patient could have. This is called "spectrum bias". It means that the test only looks at a certain part of the "sickness rainbow" and might not be able to see all of the different colors.

It's important for doctors to know about spectrum bias and think about all the different kinds of sicknesses that a patient might have. They should use different tests or methods to make sure they're checking for all the different shades of sickness, not just the ones that the test can see.
