Thanks a lot!

I have this question just because according to the definition of paramter in the textbook, I do think parameter should be a number.But in the exercises.There is always this kind of questions:Is the value 48% a parameter of a statistic.
What I mean population is uncertain is because sometimes you don't know the number of population.For example, You may don't how many people will be interested in voting.So what 's parameter when you don't know the definite number of population?Is that the same number with statistic?

工作学习 / 求学深造 / 有人在SENECA 学统计吗?有个问题请教.请问PARAMETER是指确切的数字呢,还是指百分比,如果POPULATION 是不确定的话,PARAMETER 该写哪个?谢谢啦. -susana(susan); 2002-9-27 (#770473@0)

Parameter usually takes the form of Greek letter. It is not a percentage. If you estimate it or you know the model, it's an actual number. It normally represents the effect on the change of one unit of one particular -jeffrey815(Smartiecat); 2002-9-27 {210} (#770526@0)
variable.

what do you mean when the population is uncertain? In any statistical studies, defining study and target population is an earlier step than coming up with the model where you introduce parameters.

Em.... -jeffrey815(Smartiecat); 2002-9-27 {378} (#770761@0)
I have no idea why your text book has question like that.

48% can be interpret as 0.48 which can be a parameter.

For example, a model Y = b1 X1 + b2 X2 + R,

where b1 denotes beta subscript 1, a parameter
X1 denotes X subscript 1

in this case, b1, which is a parameter, can take the value of 0.48 which represents 1 unit of change in X1 affect the outcome by 0.48.

统计专业是STATISTIC吗? -dddddmmmmm(Chinese-moving-west); 2002-9-29 (#774316@0)

对，统计课就是STATISTIC -happy_718(happy_718); 2002-9-29 (#774321@0)

问一下，这种学科科目一般加不加S啊? STATISTICS？ -pingle(Lucky Pingle Pie); 2002-9-30 (#774750@0)

should append an s. -starinfo(乘风); 2002-9-30 (#775445@0)
