On a national basis, natural gas has long been the dominant choice for primary heating fuel in the residential sector. Lately, electricity has been gaining market share while natural gas, distillate fuel oil, kerosene, and liquefied petroleum gas (propane) have declined.
Part of the national change in heating fuel choice can be attributed to population migrations farther west and south. But even within Census regions, electricity has been gaining market share at the expense of natural gas. The Northeast is the exception, as both natural gas and electricity have been increasing while distillate fuel oil and kerosene have declined.
In the Midwest, most homes are heated by natural gas. The Midwest also has the highest percentage of homes heated by propane, although both natural gas and propane have lost market share to electricity since 2005. The South is the only Census region where electricity is the main space heating fuel in the majority of homes. Heating fuel preferences in the West largely mirror the national average, although households in the West are more likely to use wood as their primary heating fuel or to report not using heating equipment at all.
Answer:
Factor Analysis
Explanation:
Factor analysis uses a statistical procedure to analyse given information about distinct common factors to determine the strength and influence of each factor on the other. The interdependence helps in analyzing better possibilities as it reduces number of outcomes to favorable and conforming outcomes.
Factor analysis act as a measure to measure correct and closer estimates of events interrelated to each other towards independent variables.
Answer:
The correct answer is Observation, Experimentation and Survey. These three basic designs are used in quantitative research.
Explanation:
Observational research:This represents the observation of the sample data in their elements. For instance one may elect to observe bank customers while they use the Automated Teller Machine (ATM). Mechanical observation uses a mechanical or electronic device to record customer behavior or responses to a particular marketing stimulus.
Experimentation: Experimental research is commonly used in sciences such as sociology and psychology, physics, chemistry, biology and medicine etc.
This involves is a systematic and scientific approach to research in which the researcher manipulates one or more variables, and controls and measures any change in other variables.
Survey:
There are various survey methods are there they are:
- personal interview survey
- telephone survey·
- mail surveys·
- Online surveys
In research of human subjects, a survey is a list of questions aimed at extracting specific data from a particular group of people.
Cheers!
