WebThe average score of the 9th-grade math, English, and Korean test scores were used as the outcome variable. The results showed that the fixed mindset slightly decreased during the elementary school period (4th-6th grade) but increased in the middle school (7th-9th grade). WebIn other words, a variable is a symbol for a number where the value is not known. For example, x + 5 = 10. Here “x” is a variable. The value of the variable “x” can be easily found by solving the equation. In this case, if the equation is solved, the value of the variable “x” is obtained as 5. It means that x = 5.
