Question

Which of the following is not true about doctor screenings?

1) Children are screened at two checkpoints.
2) Most parents do not seek advice until after their child is at least a year and a half.
3) The screenings have about an 85% accuracy rate.
4) None of the above

Answer 1

Children are screened at several checkpoints, not just two; many parents seek advice before a year and a half, and different screenings have varying levels of accuracy. The discrepancy in vaccination studies could be due to sampling variation.

Step-by-step explanation:

The question about doctor screenings appears to have misconceptions. Firstly, children are typically screened for developmental and health issues at several checkpoints, not just two. These usually align with well-child visits that occur at different stages of their early years. Secondly, while parental behavior can vary, many parents seek advice prior to their child reaching a year and a half, especially due to scheduled pediatric appointments that include screenings.

Finally, the statement regarding an 85% accuracy rate for screenings cannot be universally applied since different screenings have different levels of accuracy depending on the disease and population.

The discrepancy in vaccination rates from two independent studies showing 84% and 86% can likely be attributed to natural variation within sampling and does not necessarily point to a significant difference.
