Regression analysis uses only two of the historical data points for estimating a cost equation. true or false

The answer is false.

Explanation:

Regression analysis can take TWO OR MORE variables of interest.

It is a very useful method for statistical analysis because it allows you to compare one or more dependent variables to one independent variable. This way it's possible to measure which ones have an impact on any topic of interest, and decide which of the variables matter, which ones are irrelevant and what effect they have on each other.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
