Mini Research's Journal

From the mini research that my group mate and I have done, I can learn about how to make an objectuve report that can be read by everyone in all ages with the common word to express a technical word in the books, then I can learn how to make a good report based on the data that I got.

In the mini research projject, I have chosen married data from the population in United States in 2009. To research this data, I used four lectures that I have learnt from my respective tutor. The first lecture is about descriptive data, from this lecture, in my research I can know about the average of the population in the US that have already married, the median of the data and so on. The second lecture is about confidence interval. This lecture told me about the average of the population when they have 90% confident and 95% confident in this data. Third lecture is about the hypothesis. Hypothesis lecture is about the significant of the 30 data that I have research that the function is about to find a sufficient evidence whether to reject the first variable or to accept another variable in this case.

The last lecture is about regression. In this lecture, it shows us about the relationship between two variables in the data and the equation of the regression, it can detemine if the relationship between the two data is a strong positive relationship or strong negative relationship when it is in lower or upper some certain percentage.

Quantitative Methods

Reflective Journal 1

Topic : What have you learnt from the first 3 lectures ?

In first lecture with the topic “ Introduction to Quantitative Methods & Mathematics of Finance : Simple Interest & Compound Interest “ , I have learnt about what QM actually is, how to use the formula in this subject. Simple interest is a formula that use to find how much interest that can be earned by multiple the amount that you have invested with the interest rate and also with the period of time. Compound interest is a formula which your interest will become higher each time by accumulate the amount of interest that you have plus with the loan that you lend.

For the second topic “ Mathematics of Finance : Future Value Annuity & Present Value Annuity”, I learnt about how much money that I earn in the future that have been calculated with the periodic payment, interest rate per period and the total amount of payment which is called as Future Value Annuity. As for the Present Value Annuity is how much money that I should deposit now in order to have much money in future by calculate the periodic payment with the compound interest rate per period and number of periods.

“Linear Programming” is the third lecture that I have learnt. It is about how we can solve an equation by finding the value of two variables, solve the linear equations, learn how to draw a graphic for the inequity linear.
