Types of Grass to Grow in Central Alabama. Plant warm-season grasses in central Alabama for best results in sun or partial shade. Cool-season grasses like Kentucky bluegrass, ryegrass and fine fescue do most of their growing from fall to spring, and prefer cooler temperatures. Prepare the planting site well ahead of spring planting.
Operational Definitions. To test an idea, one must gather data. This means one must relate ideas to concrete, measurable events in the world. That is why scientists need operational definitions, which are definitions that tell how to measure or detect something.
Operational Definitions. An operational definition is a detailed specification of how one would go about measuring a given variable. Operational definitions can range from very simple and straightforward to quite complex, depending on the nature of the variable and the needs of the researcher.ow this is a problem that has challenged researchers for years, and many fine operational definitions of anxiety are already available for our use. For the sake of this exercise, however, we will assume that we have to develop our own measure without benefit of much of this existing research.
