An industrial psychologist working for a particular manufacturing company was concerned that one of their four plants might have consistently more worker grievances than the others. Records are kept for a month during which Plant A had 15 grievances, Plant B had 34, Plant C had 17, and Plant D had 20. W
What the dependant and independent variables?.

Dependent: Number of Grievances

Independent: Plant

Explanation:

Dependent variables are the variables that are caused by something else, they are dependent on another variable.

Independent variables are variables that the researcher can change and thus are the cause of an effect (the effect being recorded as the dependent variable). We often change these variables so we can compare them.

Thus the thing we are observing is the varying amount of grievances across the four plants. The complaints are dependent on the plant that they came from (we are assuming one plant treats workers poorly) and thus the number of complaints is dependent on which plant.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
