The first group was placed in a room with very bright lights and the second group was placed in a room with more normal lighting.
Individuals in the first group did better in the IQ test and she found that the difference between the two scores was statistically significant.
We say that a result is <u>"statistically significant" when it is not likely to occur randomly but rather is likely to be attributable to a specific cause.</u>
