Answer: i'd say your best bet is C
Answer:
<em>The Study of Developmental Psychology is important because</em><em> it shows us how humans learn, mature, and adapt at different stages of their lives.</em>
Explanation:
"Developmental psychologists study how people grow, develop and adapt at different life stages. They conduct research designed to help people reach their full potential — for example, studying the difference between learning styles in babies and adults."
Answer:
c. Instrumentation
Explanation:
In research methods and statistics, mainly there are eight different types of threats associated with the internal validity including experimental mortality, regression, interaction of threats, selection, history, testing, maturation, and instrumentation.
Instrumentation: The term "instrumentation" is described as one of the different types of internal validity threat that encompasses the change in the scores, instruments, or observers that may produce a few changes in the outcomes of a particular study.
In the question above, the given statement represents "instrumentation".
The correct answer is :
An upper body performance test known as the sitting medicine ball throw (SMBT) is used to assess muscular health in older people. The aim of this study was to assess the test-retest reliability and validity of the SMBT in older women. In this study, 35 ladies (mean age: 75.15 + 6.39 years) took part. Over the course of three sessions, subjects completed SMBT trials utilising standard ball masses (SMBT4 lb and SMBT3 kg). On the first day, instruction in the SMBT and chest press 1 repetition maximum (CP1RM) was given. The tests were repeated on day 2, but data were recorded. On day 3, SMBT was retested, and then chest press peak power (CPPP) values between 30 and 80 percent of CP1RM were assessed.
The CPPP and SMBT4lb (r = 0.775, p 0.001) and SMBT3kg (r = 0.734, p 0.001) exhibited significant relationships (p 0.05), and the SMBT distance showed expected ageing reductions (r = -0.724 to -0.626, p 0.001), proving its validity. There was found to be high reliability between testing days, and Bland-Altman plots revealed few locations that deviated significantly from the bounds of agreement. The SMBT is a valid and incredibly trustworthy instrument that health providers can use to track upper body muscular power deficits in older women and enhance treatment regimens.
