Therefore, it could be argued when comparing and contrasting the two approaches, it is crucial to look at the advantages and disadvantages of the two. The main advantages of the experimental method is the ability to control what each participant experiences and this allows researchers to test precise and accurate hypotheses and draw conclusions about how one variable affects another. The main disadvantage of is that it cannot replicate or reproduce the complexity of real life and it can miss social rules and other factors that could establish whether a bystander intervenes or not. The discourse analysis, on the other hand can capture a richer and more varied picture of people’s experiences and looks at people’s actual experiences. However, it cannot provide general rules about human behaviour that could be applied to more than one
The SAT and ACT tests only check to see what vocabulary the student has and how quickly they can come up with the correct answer. The math sections just find out if the student is able to come up with the correct answer with the amount of time given. This causes serious concern due to the fact that students will not be on as much of a time crunch when they are doing their work for college classes, which are what these standardized tests are designed to predict. Because of this, it is not reasonable to assess a student’s abilities solely based off of their test
Also the error bars on the time distance are present but they are so small it is not a significant enough number to show on the graph. The error bars are the same as the uncertainty on the instruments. The data points on the graph show that the line of best fit includes all the data within the error bars and so the data is moderately precise and the results are reliable. The limitations of the experiment were that the exact measurement of the distance and time were both done by hand and so there is human error involved. Also we can see that because the data was taken at a certain time the results will not work for all times of the day.
According to Corder (1971) mistakes are deviation due to performance factors such as memory limitations, spelling pronunciations, fatigue, emotional strain, etc. They are typically random and are readily they can be self-corrected when attention is called. Whereas, an error is the use of linguistic item in that a fluent or native speaker of the language regards it as showing faulty or incomplete learning. In other words, it occurs because the learner does not know what is correct, and thus it cannot be self-corrected. These are systematic and consistent deviances.
The exams that are administered are at some point reliable because they discriminate the weak from the strong candidates and there is also consistency in the scores the learners obtain in a certain period of time. However, a study needs to be conducted in order to find out whether some other human factors may affect the results obtained by the learners. There’s also a need to discuss the degree in which reliability is affected when certain protocols when administering the tests are either unknown or
It has to a certain extent been receiving criticism for the last decades. This resulting in all the performance tasks being used in this study are prepared in contextualised, to a different degree and in real-world scenarios. There are other ways to approach these tasks which can be concluded with a variety of answers. The following is an example of a performance task which is authentic and can be used in the local social
Since the value is negligible, it can be concluded that the sources of errors were minimal. Summary and Conclusion In a nutshell, the lab managed to meet its sole objective. However, systematic errors occurred during the experiment. These errors can be minimized by making sure that the orifice meter is calibrated accurately. References Cochard, Hervé.
There are three major theories of the causes of error. The first theory is coined by Hubbard et al. (1983). They proposed that they are three major causes of errors. They are mother tongue interference, over-generalization and errors caused by the teaching method or the teaching material.
Chapter 7 Errors in Measurement Systems Errors in the measurement of a physical quantity are defined as its deviation from actual value. Understanding the factors that contributes to measurement errors is very important. This helps to determine and design the appropriate measures to improve accuracy of the instruments up to the larger extent possible.. Measurement errors are classified into following main categories Measurement Error Any measurement made with measuring devices or instruments is approximate to certain extent. If the measurand of certain quantities are repeatedly measured a number of times, measured value may not be the exactly same.
