Goldilocks Effect: Read to Your Kids! The American Academy of Pediatrics recommends that parents begin reading to their children soon after birth, and that parents set limits on screen time. A new study¹ reinforces these recommendations. In the study, 27 four- year-olds were presented with stories in three different formats: audio (sound only), illustrated (sound and pictures), and animated (sound and animation). During the presentations, a magnetic resonance imaging (MRI) machine measured each child's brain connectivity. The researchers found a "Goldilocks effect," in which audio was too cold (with low brain connectivity as the children strained to understand) and animation was too hot (with low brain connectivity as the animation did all the work for the children). The highest connectivity (just right!) was found with the illustrated format, which simulates reading a book to a child. 1.

Question

In this same passage, you gave me the answer about how many cases and that is not correct.  Here is the explanation of the definition of the cases.  And then, how many cases in this same passage?

Goldilocks Effect: Read to Your Kids! The American Academy of Pediatrics recommends that parents begin reading to their children
soon after birth, and that parents set limits on screen time. A new study¹ reinforces these recommendations. In the study, 27 four-
year-olds were presented with stories in three different formats: audio (sound only), illustrated (sound and pictures), and animated
(sound and animation). During the presentations, a magnetic resonance imaging (MRI) machine measured each child's brain
connectivity. The researchers found a "Goldilocks effect," in which audio was too cold (with low brain connectivity as the children
strained to understand) and animation was too hot (with low brain connectivity as the animation did all the work for the children). The
highest connectivity (just right!) was found with the illustrated format, which simulates reading a book to a child.

We obtain information about cases or units in a dataset, and generally record the information for each case in a row of a data
table. A variable is any characteristic that is recorded for each case. The variables generally correspond to the columns in a
data table.
