Statistic

So, t will be our test statistic. In our case, the computed value of t is .341, which is well within the zone of acceptance. So we can accept the hypothesis that μ = 7. The Independent Samples t-Test can only associate the means for two (and only two) groups. It cannot make comparisons…

Carpi and Egger’s reading “Uncertainty, Error, and Confidence” discusses how there will always be a small portion of error in all scientist’s works. However, there are two different types of error: statistical and systematic and the main difference between the two is that statistical error is random and systematic error can be compensated for during an experiment. Scientists do not report just a single value as a measurement due to these types of errors in experiments, they report a certain…

Analysis BASE-6 Analysis Jacobson-Truax Classifications. The first step in analysis was to classify each participant according to the Jacobson-Truax framework. Descriptive statistics resulting from this process can be seen in Table 5. According to this framework, the majority of clients either recovered or did not significantly change. Those in the improved class began on average with the highest score (representing most severe symptoms) but also improved the most on average, even slightly more…

Is America’s academic “boat” being taken over by the Chinese? In the New York Times article, “Amy Chua is a Wimp”, by David Brooks, touches on whether Chinese parenting is better than American parenting, and criticizes one parent’s, Amy Chua, method of raising her own kids. In this piece, Brook uses effective literary strategies in order to turn us against Chua, but at the same time opens our eyes to the idea that she is no better than us Americans. He exploits Chua’s parenting flaws right from…

ABSTRACT Using remote sensing technology is an effective way to observe and verify the wise and sustainable use of natural resources. With its weather and daylight independency Synthetic Aperture Radar (SAR) data emphasize as particularly suitable for large-scaled monitoring. But the classification of SAR images is more difficult as of multi-spectral images. Because of the microwave’s interaction with the object parameters on the earth surface, like roughness or the complex dielectric…

MEDSCI 725: EXPERIMENTAL DESIGN Ellynn Sy ANCOVA and More Complex Designs (Parametric Tests) Introduction Analysis of covariance (ANCOVA) is most frequently used to refer to the statistical technique that combines regression and ANOVA [1]. It offers a way to obtain a more precise assessment of the effect of the experimental manipulations on the dependent variable. An ANCOVA design requires the measurement of one or more other variables. These variables are covariates, predictor, variables,…

their teen about what is appropriate or inappropriate conduct in school, at home and in their social lives, with 56% saying they have these conversations frequently”(Anderson 2016:11). Another example and answer to the question at hand are more statistics that were found to be true, “39% frequently discuss the online content their teen views; 36% frequently discuss appropriate television, music, books, magazines or other media; while another 36% frequently talk with their teen about their online…

INTRODUCTION In business field, there are many uncertain situations business owners and managers would face. In order to make a decision about their businesses, the managers need analyzed information, which could be provided by statistic method. AJ Davis department store, a chain store, wants to analysis the credit customers so the sample data of 50 credit customers was collected. The manager at the store has speculated some information about credit customers. By using the sample data of 50…

the nondominant hand, we measured an average of 21.25 kg for maximum clench strength before fatigue, an average of 19.75 after fatigue, an average of 35.25 seconds for clench duration before fatigue, and an average of 29 seconds after fatigue. The statistics on collected data indicated that when it came to the maximum grip strength, there was no significant difference before or after the arm muscles had been fatigued, or between the dominant and nondominant hands. In addition, the results also…

precisely. All statistical analysis will be carried out using the (SPSS). All the data should be browsed and treated for errors and missing value. This research uses descriptive, reliability test, correlation and linear regression analysis. Descriptive statistics are used to describe the basic features of the data in a study. They provide simple summaries about the sample and the measures. Together with simple graphics analysis, they form the basis of virtually every quantitative analysis of…
