Answer: The Marie Curie School.
Step-by-step explanation:
Intelligence tests are designed to assess people's cognitive abilities or skills based on problems that involve decision making, reflecting, or deducing to obtain the correct answer. The result obtained is known as Intelligence quotient (IQ); this result helps to compare the results of a subject with those of his age group. The average IQ of an age group is 100. When is obtained a lower result, the person is a delay compared to the age group, and when the result is higher, the person is considered to have a greater capacity.
The standard deviation is used in statistics to quantify the variation of a set of data. A low deviation indicates that the data extends over a range of reduced values, a high deviation to the contrary; indicates that the data extends over a wide range of values.
In this case, the fact that The Marie Curie School reports a standard deviation of 15.6 indicates that the data extends over a broader range of values than the Einstein School. So it is more likely that the school has children with more diverse abilities.
