Find a Missing Value From a Target Mean
Written by Adi Ackerman, Head Teacher
"Find a Missing Value From a Target Mean" is written for 7th Grade (Ages 12-13). A 6th grader who is already steady on data & graphing can use it too, and an older student can use it as a short review.
7th grade math worksheet: write an equation from a target mean and solve for the missing value x in a data set. Answer key included. Part of our comparing populations and sampling data & graphing collection.
How do I use this worksheet?
Use the center and range sheets first, then the comparison sheets. The claims sheet works well for discussion.
What students will practice
- Students will write an equation using the mean of a data set with one value missing.
- Students will solve for the missing value x.
- Students will work with whole numbers, negative numbers and decimals.

FAQ
How do I use this comparing populations and sampling worksheet?
⌄
Use the center and range sheets first, then the comparison sheets. The claims sheet works well for discussion.
What does this worksheet teach?
⌄
Write an equation from a target mean and solve for the missing value x in a data set. The directions on the page read: Write an equation using the mean, then solve for the missing value x. An answer key is included.
Can I use this comparing populations and sampling worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade data & graphing, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
How do you compare two groups using data?
⌄
Find a measure of center such as mean or median for each group, then compare them. Add a measure of spread such as the range to describe variation.
How do you find a missing value from a mean?
⌄
Write an equation with the sum of the values divided by their count equal to the mean, then solve for x. The Find a Missing Value From a Target Mean worksheet does this.
How do you find the median of an even-sized set?
⌄
Put the values in order, then find the number halfway between the two middle values. The Median of Even-Sized Sets worksheet uses rational values.
Do these worksheets have answer keys?
⌄
Yes. All 11 worksheets in this group have answer keys.
