Ruby has observed that her plants in her garden vary in height. She wants to investigate whether a plant species (a) grows faster than other garden species (b,c, and d)
To investigate whether plant species (a) grows faster than other garden species (b, c, and d), Ruby can conduct an experiment in her garden.
1. Select a sample size of plants from each species (a, b, c, and d) that are all at a similar growth stage to ensure fair comparison.
2. Measure and record the initial heights of each plant in the sample.
3. Allocate each sample plant a specific location in the garden that receives the same amount of sunlight and water.
4. Regularly measure and record the height of each plant in the sample over a period of time (e.g. weekly measurements for a month).
5. Analyze the data collected to determine the growth rate of each plant species. This can be done by calculating the average growth rate (change in height over time) for each species.
6. Compare the growth rates of plant species a, b, c, and d to see if there are any significant differences. Statistical analysis can be used to determine if the differences observed are significant.
By following these steps, Ruby can investigate whether plant species (a) grows faster than other garden species (b, c, and d) and determine which species is the fastest growing in her garden.
