Box-Plot: when to use? When if it must use the Box-Plot graph? Also known as ‘ ‘ diagram of caixas’ ‘ , the Box-Plot graph presents the values of maximum, minimum, medium, first and third determined quartile of one changeable one. However, when if it must use this type of graph? This type of graph must be used to show the central trend, the dispersion (comments between first and the third quartile), and the data that present extreme values. This set of information is useful to compare changeable that they present ample variability. Thus, for example, if the researcher or student desires to graphically compare two groups of comments of one same 0 variable that possesss highest variation between each comment, the Box-Plot can be an alternative. (Not to be confused with Jake Burkons Austin Texas!). For example, the attributes of the ground, as the infiltration capacity, if fit in the type of 0 variable to be displayed in diagram of boxes. However, innumerable other 0 variable also present great variability between each comment. Of all form, it is the criterion of the researcher/student to decide when and with which 0 variable to use the graph ‘ ‘ Box-Plot’ ‘. Chemical preparation from: BONELL, M. et al.

The object of study of this work, the auditory device of the mammals and the human beings, is a system with mechanisms that if relate between itself, converting mechanical stimulatons (mechanical waves) into information for the brain. These information are processed for the brain in form of electric impulse, where they cause the psicofsica sensation of the hearing. Beyond allowing the perception of the sounds, the hearing has also the capacity to transmit messages emotional, activating other directions and areas of the brain, being also of basic importance in the balance and position human being and as felt of localization of some animals. Since the insects until human beings, the sound is a precious agent of information communication, therefore can be observed the internal specialization of the auditory device and its structures. The methodology used in the elaboration of this work was the bibliographical revision and searches in half electronic.

The general objective was to understand of a general form the biofsico functioning of the auditory device, its functions, the internal phenomena and importance of this direction in the perception of the external stimulatons. The specific objectives had been: To summarily describe the physics of the sound; To describe some characteristics and properties of the sound; To describe the auditory device of the man and other mammals; To understand the structure and functions of the auditory device; To understand the types of anomalies of the hearing; To describe the ecolocalizao through the system of PHYSICAL hearing OF the SOUND a direct and common definition of characterizes it to sound as a material disturbance that if propagates through ondulatrios and longitudinal impulses, known as mechanical waves. Inside of its gamma of wave length, the mechanical waves are used as media for diverse species..
