Comparing Plant Growth under Two Treatments

Analyze plant growth outcomes resulting from two different experimental treatments. Compare center and spread to evaluate differences in plant development.

Questions

  1. MultiChoice

    Treatment A median growth = 14 cm, Treatment B median growth = 20 cm. Which treatment yielded more typical growth?

  2. MultiChoice

    Treatment A IQR = 3 cm, Treatment B IQR = 7 cm. Which treatment produced more consistent growth in the middle 50%?

  3. MultiChoice

    Median growth A = 14 cm, B = 20 cm. What is the difference between medians?

  4. MultiChoice

    Treatment A Q1=12, Q3=15 (IQR=3). Treatment B Q1=16, Q3=23 (IQR=7). What is the ratio of IQR B to IQR A?

  5. MultiChoice

    Fertilizer 1 median growth = 8 cm, Fertilizer 2 median growth = 8 cm. What is true about their centers?

  6. MultiChoice

    Fertilizer 1 IQR = 2 cm, Fertilizer 2 IQR = 6 cm. How many times larger is Fertilizer 2 IQR?

  7. MultiChoice
