It is well known that the temperature that a plant is grown in greatly affects the manner in which that plant grows. If the conditions are too extreme for a plant, then that plant cannot be as productive as other members of its species grown at less extreme temperatures. Such is the case of the pepper or tomato plant; if temperatures are too high for these plants, then the pollen these plants produce becomes inviable and these plants cannot successfully reproduce (Environmental Factors That……

3.8.2 Geary’s C Another measure of spatial autocorrelation is Geary’s C statistic which ranges from 0 to 2 where 0 signifies maximum positive spatial autocorrelation or clustering, 1 signifies no autocorrelation or randomness and 2 signifies maximum negative autocorrelation or dispersal. If the values of Geary’s C are low it indicates positive spatial autocorrelation and if the values are high it indicates negative spatial autocorrelation. The calculation is similar to Moran’s I but here the…

measures of associations refers to the statistical strength of the relationship between the variables of interest. This can be described in numerous ways; this also depends on the analysis. This is concerned with how each variable is related to other similar variables. This association is based on the strength of the linear relationship in the degree of monotonicity. To the degree that it is based on counting various pairs in a relationship. Known as a statistical tool that investigates…

statistically significant data or results. Further tests could have been done with an increased sample size that could possibly yield at statistically significant p-value. By modifying the messages for future tests, we could be able to increase the statistical significance of the results. We could create a very bland message with all the writing the same size black and white, boring font, then we could create a colorful message with different fonts and font sizes that is appealing to the…

to grow in all countries with the only difference in period when the impact reaches its peak. However, not all impulse response functions are statistically significant. In this paper statistical significance is tested by analysing confidence intervals. It has become standard in relevant papers to evaluate statistical significance using upper and lower limits of impulse response functions. “An easy way of assessing whether any of these responses is significantly different from zero is to search…

Statistical Research An interesting topic to study would be the way geriatric patients are being treated in health care facilities. This is because as the elderly are getting closer to the end of their lives, many are starting to decline. Meaning that the elderly can become less verbal, making it harder for them to communicate and carry a conversation. Therefore, does this make it harder on the caregiver to provide the proper care? For an example, as the nurse taking care of an elderly…

Introduction Prosopagnosia is a cognitive disorder in which facial recognition is impaired, while other aspects of visual processing remains intact (Gruter 2008). This disorder implies that the brain processes visual stimuli differently. Using the Memory Interference Test (MIT) aggregated database, students can formulate hypotheses based on demographics by studying the number of correct responses and mean reaction time by observing pre-calculated students t-test. This particular assessment…

(Harrington, Bosch, Schools, Beel-Bates, Anderson) Yes statistical significance was presented and insignificant. The results were not compelling findings. Many of the test scores did not show which testing style was more appropriate to teach with. Limitations are constricting to studies and this one holds a large…

The third problem was chosen to demonstrate the use of a method described in Rand Wilcox’s book [4] and implemented as a Minitab® macro in the diskette accompanying the book [5]. In class discussions lead to my interest in Yuen’s test of trimmed means which is appropriate for situations when there is evidence of non-normality and heteroscedasticity [4]. If there is no violation of normality but there’s is heteroscedasticity, the Yuen’s test without trimming, which is actually the classical…

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…
