Verified step by step guidance

1. Understand the concept of prevalence in psychology, which refers to the proportion of individuals in a population who have a particular condition at a given time.
2. Recognize that dyslexia is a common learning disorder characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities.
3. Recall epidemiological research findings that estimate the prevalence of dyslexia to be around 10–15 percent of the population, making it a relatively common condition.
4. Evaluate each statement by comparing it to the known prevalence data: less than 1 percent is too low, over 50 percent is too high, and dyslexia is present in both children and adults, not only adults.
5. Conclude that the accurate statement is the one indicating dyslexia affects approximately 10–15 percent of the population, reflecting current scientific consensus.
