ensure the relevant issues was examined in a comprehensive manner. Statistical tools and methods used where appropriate for analyzing the relationship among the variables and the model. 3.8.1) Descriptive statistics analysis The data that had collected will analyze based on the descriptive statistics analysis. According to You, Chen and Liu (2014), descriptive analysis technique is used to collect actual information in detail and to describe characteristics of certain groups. Descriptive…

that is influenced by sample size. Slide 8: Another term that you will report about your statistical results or findings is the ‘degrees of freedom.’ This term refers to how many values are free to vary in a set of values if we know the summary statistic and the number of values in the set; how many values would we need to know in order to deduce the remaining values. It is sued to compensate for the bias that occurs when calculating for large standard deviations found in small sample sizes.…

2013) . For example, looking at the box plot it clear that the frequency is up to 75, but the outliers are displayed (beyond the range of data) 76 or more in this data signify a problem in the data (Triola, 2008) . Descriptive Statistics Figure 2 Descriptive Statistics Figure…

analysis method was the MSER technique. MSER seeks to determine an optimal truncation point that helps mitigate bias without losing precision in our results. Using the data generated from the replication/deletion method, we generated the MSER statistics using the Ruby script, mser.rb. The script created a data file with 10 different means (x ̅) and the remaining observations after truncation (n), outlined in Table 2. We will refer to n as our sample size for each run. The MSER technique used…

only research design that allows researchers to infer causation is experimental designs. Therefore, in order to prove (or disprove) a causal relationship between vitamins and crime rates, an experiment must be designed. One of the key principles in statistics is “correlation does not equal causation.” Any two independent variables could happen to be correlated, but that does not show a cause-and-effect relationship between the two variables. The two variables researched through a…

MIAA showed a correlation of -0.026, meaning there is no correlation between the two variables. The statistical tests used were both a bootstrap test and a randomization hypothesis test for a correlation. Figure 1. Scatter plot and summary statistics from the sample data. This display has the time in seconds on the X-axis and the distance in miles on the Y-axis. Then, to examine if the distance traveled has any impact on the speed of the athlete, a randomization hypothesis test…

Method The study done used the dataset from the General Social Survey (2014). It has been brought forth by the University of Chicago. The GSS monitors societal change and studying the different variations of American society. The survey aims to gather data on American society so that they can monitor and explain the different trends and constants in the attitudes, behaviors, and attributes in the nation’s culture. Some other things that they look at is the structure and functioning of society…

decreased ability to use insulin effectively is what leads to the disease process causing multiple body systems to undergo changes as a result (Shrivastava, 2013). DM can be classified into two categories: Type 1 or Type 2. The National Diabetes Statistics Report 2014, consensus that 29.1 million individuals (9.3%) of the U.S population have diabetes. Of the 29.1 million individuals, 21 million are diagnosed and 8.1 million are unaware that they have the disease. The racial and ethnic difference…

Zonal statistics function summarizes the value of a raster within the zones of another dataset (either raster or vector) and reports the results as a Table. Maps of LU/LC, NDVI and LST were prepared for the year 1989, 1999 and 2016. To examine the spatial difference of LST according to varies LU/LC; the result was summarized using the zonal statistics tool of the ArcGIS 10. 3. subsequently, summarized LU/LC, NDVI and LST map data were analyzed using excel. Zonal statistics as table is one…

the actuaries as they did statistical analysis through the program RAT-STATS. This program allowed them to choose what kind of test to run, and in return, it would choose exactly which data was to be used from the large sample. It also gave test statistics. I don’t have a lot of experience with analytical research; however I have taken some classes that required me to write an analytical research paper. As I mentioned in question one, I have taken courses that focused on teaching the basics…
