Look on the bright side‚ as Miss Lan Phuong said above‚ we will harvest many things via working such as finance‚ chance to more mature‚ widen the relationship‚ and better understanding our self. However‚ it doesn’t mean that all the students should immediately get out of the house and get a job‚ there are some disadvantages should be considered:

Test One 1. Compare experimental and co relational methods. What are the advantages and disadvantages of each? Show by an example how both methods could be used to investigate the same problem. Co relational method is a scientific procedure that is used to look for relationships between variables. On the other hand‚ experimental method is a scientific technique that involves a sequence of procedures which include observation‚ identification

An Introduction to univariate financial time series analysis 1 Introduction: what is a time-series? Time-series is a sequence {x1‚ x2‚ ...‚ xT } or {xt} ‚ t = 1‚ ...‚ T‚ where t is an index denoting the period in time in which x occurs. We shall treat xt as a random variable; hence‚ a time-series is a sequence of random variables ordered in time. Such a sequence is known as a stochastic process. The probability structure of a sequence of random variables is determined by the joint distribution

from the descriptions of social life provided by participant observation and unstructured interviews to information from written sources. Quantitative data is usually in the form of statistics. Questionnaires and structured interviews are typical methods used when gaining quantitative data‚ as the results are easily transferable to a numerical form. Qualitative data is associated with participant observation‚ it can include unstructured interviews‚ information from written sources such as diaries

very beneficial. However‚ before deciding to take a part-time job‚ they should take other disadvantages—lacking time to study‚ for example--into consideration. First of all‚ engaging in part-time jobs enables students to learn new things that they cannot learn from their books and schools. For example‚ a student can learn how to do their school-works or assignments when studying in their classes‚ but they cannot learn how to manage their time effectively‚ how to arrange their many works appropriately
