1057 Words5 Pages

Introduction_______________________________________________________________
In this essay I will attempt to critically analyse the above statement by accessing the validity and reliability in a number of assessments. First of all we need to pass a critical eye over both validity and reliability. The statement above states that these are the foundations of underpinning assessments. But what exactly does validity and reliability mean? The definitions for these terms are,
Reliability is the extent to which an "experiment, test, or any measuring procedure yields the same results on repeated trials. Validity is the extent to which the construct measures what it says it is measuring. ’One validates, not a test, but an interoperation of data arising …show more content…

They were found to be unacceptable for research as they all needed to be individually calibrated. Nowadays however electronic pedometers have been found to be more reliable than the older mechanical ones. The electronic pedometers are triggered by vertical accelerations of the waist which occur when walking. They are worn on the hip of your leg. Upon each step a horizontal spring-suspended pendulum arm moves up and down, opening and closing an electrical circuit meaning that would be one step recorded. Pedometers however can sometimes not be too reliable and break down very easy or be out of range with their step count. One model (Yamax DW-500) recorded results close to 2% of the actual values.
Electronic Pedometers do have limitations such as research tools according to Freedom and Miller (2000). They cannot distinguish between walking and running. Electronic does not distinguish speed, it assumes that a person expends a constant amount of energy per step. Pedometers also lack memory for data storage and lack adequate internal clocks meaning that there is no reliable information regarding the time or intensity of the physical …show more content…

They validated the sample of 228 youth players which was clearly stated in the titles. These youth players were then classified into two different groups according to their level. They were divided in elite and sub elite groups. The present differences found between players of different competitive levels (elite and sub elite) further supports the contract validity of this test for measuring the ability to repeat high-intensive intermittent exercise in young soccer

    Introduction In the teaching profession, exploring a relationship between reliability and validity gives profession educators an understanding of rather their tests/ assessments is reliable/ unreliable or valid/ invalid. In other words, to fully understand the relationship between the two concepts, the profession educators will definitely know the type of testing to measure the understanding of their students. If a teacher does not understand the two concepts and their relationship, that teacher will end up giving students unreliable tests throughout the school year. Therefore, profession educators should know the relationship between reliability and validity in order for them to survive in the teaching field in the future.
