Read the following passage which contains an argument for a causal claim. Does the evidence cited provide a compelling reason to accept the claim that there is a causal link between time spent watching videos online and academic performance in primary school children? Explain your answer.

A new study indicates that watching videos and shows online on sites like YouTube and Netflix may be negatively impacting young children's academic performance. In one of the largest studies of its kind, researchers were granted access to hundreds of thousands of test scores of primary school age children. Along with this data they gathered survey responses from the parents of the children, asking how many hours a day they estimated their child spent streaming videos online. They discovered that those children who watched over four hours of video content per day were significantly more likely to perform worse than average on standardized tests, compared with children who watched less than four hours per day.
