How might you use a number line to determine if certain solutions are valid?

An assessment is valid when it measures the content that was taught and when it reflects the content and skills you emphasize when teaching the course. Validity is critical because educators make inferences from assessment scores about student achievement or mastery of content.

Step-by-step explanation:For a test to be reliable, it also needs to be valid. For example, if your scale is off by 5 lbs, it reads your weight every day with an excess of 5lbs. The scale is reliable because it consistently reports the same weight every day, but it is not valid because it adds 5lbs to your true weight.Reliability and validity are both about how well a method measures something: Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).
