estimation is to think of an answer before measuring the quantity and approximation is to round off.

Mr. Kevin thinks that estimation can help students get real sense of conversion between fraction and percentage.

The distance from the origin at time t, in the direction of motion, is the area under the graph between time 0 and time t. In a simple speed-time graph the area may be calculated using simple formulae for the areas of triangles, rectangles, trapeziums. In more complicated cases you will need to integrate for the area under the speed-time curve. And in seriously complex cases, you will have to use numerical estimation for the area.

Advantages:The nature of the relationship is generally easier to see: linear, polynomial, exponential, power etc;The range and domain of the data sets are immediately apparent,Estimation for intermediate values (interpolation) is relatively straightforward.Disadvantages:Not very useful if the observations are unevenly spread over a large range or domain (very skewed distribution).Exact values not given,Exact parameters describing relationship not available,Tendency of naive users to extrapolate.

The residuals in regression estimation are estimates of error. Most commonly, the errors are assumed to be statistically independent, identically distributed and normally distributed, that is, to have a Gaussian distribution.If these were the assumptions under which the regression was calculated then the residuals could (at least potentially) be examined for any departures from the assumptions. Usually they are plotted against the independent variable to see if there is any systematic relationship between the two sets of values. The residuals might also be tested for normality.It's worth reading more about this subject.

estimation is how much you think it would costs and budget is how much you decide it will cost after several estimations. budget is how much you can spend.

The difference between a measurement and an estimation is that a measurement is an exact data while an estimation is a guess as to what something may measure. For example, you can use a ruler to get the exact measurements of a piece of paper. However, if you don't have a ruler, you can make an educated guess as to what the paper's length and width measurements may be.

The most difference is on cost estimation. In PreFS, cost estimation is based on assumptions while cost estimation in FS is normally based on vendors' offers/proposals, at least for expensive price equipment/materials.
