Dr. Aris wanted to investigate whether toddlers aged 2 to 3 years old prefer playing with a novel interactive digital whiteboard or traditional finger-painting. She set up both activities in a specialized play-laboratory at a university and filmed the children's choices from behind a one-way mirror to see which activity they chose to play with first.
Dr. Aris's results are shown in Table 1.
| Gender of child | Digital whiteboard | Finger-painting |
|---|---|---|
| Boys | 8 | 4 |
| Girls | 3 | 9 |
