You are collecting data on plant growth. There are 10 plants, and you measure each one every week for 4 weeks. What matrix should you use to organize the data?
1.4×1
2.1×4
3.4×10
4.10×4
4. 10×4
You would have 10 rows (one for each plant) and 4 columns (one for each week of measurements) to organize the data on plant growth.
