Question

An agricultural research expert was interested to know the effectiveness and effect of two different types of fertilizers (A and B) on the growth of the plant. She designed a study whereby air, water and temperature were controlled in the laboratory. Each of the two fertilizers was put to the same plan with 5cm height. After two months, results appeared as indicated in the following Table

Type of fertilizer	Height before	Height After
Fertilizer A	5cm	17.8
Fertilizer B	5cm	8.3

Based on the information above, what kind of research design the researcher used? (10%) What interpretation can you deduce from this study? (10%) What kind of analysis will you perform in order to know if the plant heights after fertilizer were different? (5%)

Answer 1

Based on the information above,

Experimental research design the researcher used.

From this study we can deduce that the fertilizer A has more effect than fertilizer B.

Predictive analysis will you perform in order to know if the plant heights after fertilizer were different. Because the various types of methods that analyze current and historical facts to make predictions about future events. In essence, to use the data on some objects to predict values for another object.
