J what is the IQ are for Jacob's data set the numbers are 13 216 so we have 13 13 1/2 14, 14 1/2 15 15 1/2 and 16
To find the IQ range for Jacob's data set, we need to calculate the difference between the highest and lowest values in the set. The highest value in the set is 216 and the lowest value is 13, so the IQ range would be 216 - 13 = 203.
Next, we need to divide the IQ range by 5 to find the IQ intervals. This gives us 203 / 5 = 40.6. Since IQ scores are typically whole numbers, we can round this down to 40.
Therefore, the IQ intervals for Jacob's data set are: 13, 13 + 40 = 53, 53 + 40 = 93, 93 + 40 = 133, 133 + 40 = 173, and 173 + 40 = 213.
