Sally is 15 years old. However, she acts more likely a 12-year-old and her recent assessment with an IQ test revealed that, in fact, she does have a mental age of 12. based on terminus ratio IQ equation, what is Sally's IQ a. 12 b. 80 c. 125 d. 105
b. 80
In an IQ test, those scoring within one standard deviation would score between a. 85 to 115 b. 90 to 100 c. 70 to 135 d. 80 to 120
a. 85 to 115
To determine Sally's IQ using the terminus ratio IQ equation, we need to compare her mental age (12 years) to her chronological age (15 years) and multiply it by 100. The terminus ratio IQ equation is calculated as follows:
IQ = (Mental Age / Chronological Age) * 100
Let's plug in the values:
IQ = (12 / 15) * 100
Calculating this equation, we find:
IQ = 0.8 * 100
IQ = 80
So, based on the terminus ratio IQ equation, Sally's IQ is 80. Therefore, the correct answer is (b) 80.
