Standard score is independent of unit of measurement. Is this statement true or false?
Answer
"Standard score is independent of unit of measurement."
It is a true statement.In a normal distribution $Q _3= m +$ $0.675 \sigma$.
Therefore, $Q _3=13.25+0.675(10)$ $-13.25+6.75=20$.
Thus, estimate value of its third quartile is $20 .$
The additive model of the time series is as follows : $y_t= T _{ t }+ {S _{ t }}^i+ C _{ t }+ R _{ t }$
where, $y_t=$ Variable quantity,
$T _{ t }=\text { Trend, } $
$S _{ t }=\text { Seasonal Component, }$
$C _{ t }=\text { Cyclical component, } $
$R _{ t }=\text { Random component. }$
If there are simultaneous changes in the values of two variables due to direct or indirect cause effect then it is said that there is correlation between two variables.
When the price of an item is compared with the price of the same item in some specific $($fixed$)$ year of the past, then that specific year is called the base year.
