1 (b) Ordinal: An ordinal variable has qualitative categories that are ordered in terms of degree or magnitude. Forecasting is the process of making predictions of the future based on past and present data and most commonly by analysis of trends. %���� Companies use a qualitative method of forecasting to analyse and evaluate the opinion of experienced staff rather than focusing on numerical values (Dwyer, et al., 2012). •Its purpose is to obtain in-depth information on concepts, perceptions and ideas of a group. 0000020451 00000 n stream cement, and build material. •A FGD is a qualitative method.

While there are a wide range of frequently used quantitative budget forecasting tools, in this article we focus on the top four methods: (1) straight-line, (2) moving average, (3) simple linear regression, and (4) multiple linear regression.
