Student's t-test

Binomial Test. A study was conducted to explore whether Kayden Real Estate rent more than 35% of their rental properties to families. In a random sample of 70 rental properties, only 24% were rented to families. This is less than the target set by the government authority (35%) and a Binomial test shows that the difference is significant, n = 70, p = 0.037. The 95% confidence interval indicates that between

experiment. Materials and Apparatus A pool of 208 words were selected and divided into two sets of 104 words each. One set of words served as new words (New word set) and another set of words served as old words (Old word set) in the recognition memory test. Both sets of words were presented randomly in two different

The aim of this experiment was to basically analyze how fast the brain can perceive color and describe words simultaneously with the Stroop Effect theory. The Stroop Test is also done to determine new findings on the human’s brain automaticity and how it processes certain functions. In reference, to the independent and dependent variables involved, the independent variable in this experiment would be the color word followed by the conflicting color and the dependent would be the time that it took

causing erroneous reactions to the SM child (Dean, 2012). The experimental design below was used to determine if an increase in scores between the two related groups” before training/ after training” increased or decreased. The paired samples t-test was used to determine if differences in the scores of the SM Awareness Questionnaire occured. A survey was administered

potentially controversial issues” (Investopedia, 2016). This definition is relatable to the ethics in business school studies. The use of non-approved material or assistance can lead to questions about the collection and validity of the results in any student’s submissions. How does the two relate, and is there a correlation between cheating in school and unethical behavior in the business community? By understanding more about what is being allowed in the university, it may provide us with insight into

The data analysis and interpretation process identifies solution to the research problem. This study makes use of the statistical technique independent sample t test, F test for testing equality of variances and one way ANOVA to test the proposed hypothesis. In this research, descriptive research design makes use of the independent sample t test. Ethics in this study is strictly followed by the researcher and also data is maintained in

The result of heteroskedasticity test done for Model II is also shown in Table 5.13 below. The null hypothesis of no heteroskedasticity cannot be rejected this time too. That means the standard errors, T-statistics and F-statistics done for the model are valid.

Robust Optimization Approach to Multi-Period Portfolio Selection Progress Report Introduction Investors always seek for a way that they can get back greatest return while enjoying minimized risk. Instead of investing in a single asset, holding a portfolio is obviously less risky. However, how to select the best portfolio among tens of thousands of assets in today’s financial market? The stringent need of investors promote the raising of modern portfolio theory. In 1952, Harry Markowitz [1] established

The T-Distribution and T-Test “In probability and statistics, Student 's t-distribution (or simply the t-distribution) is a continuous probability distribution that arises when estimating the mean of a normally distributed population in situations where the sample size is small” (Narasimhan , 1996). Similar to the normal distribution, the t-distribution is symmetric and bell-shaped, but has heavier tails, meaning that it is more likely to produce values far from its mean. This makes the t-distribution
