Bernice conducts a study on the effects of violent television on children. She obtains a sample of 30 aggressive children and 30 non-aggressive children. She has the aggressive children watch 15 minutes of aggressive television and the non-aggressive children watch 15 minutes of non-aggressive television. This study represents a study.

Confounded

Explanation: A confounded study simply means an experiment or study in which a confounding or lurking variable has been introduced which will impact or cause a distortion between both the dependent and independent variable resulting in a spurious relationship.

In the scenario above, aggressive children were subjected to aggressive movies and non-aggressive children were subjected to non-aggressive movies. A lurking or confounding variable has been introduced such that a correlation or causal relationship cannot be correctly established.

answer; when one group has an extremely high score at pretest;

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
