Statistical dispersion

necessarily that it should be overly formalized or technical, but one with sound judgement. Abelson argues that good judgement with statistics in social science has been lost because there is considerable focus on null hypothesis testing (Abelson, 2). Statistical results that are shared should always be prefaced with a context and be provided with comparison groups. Also, it should never be the case for researchers to come up with an absolute conclusion once a model reaches the threshold of…

Introduction: Based on preliminary research, the hypothesis of the present study was that at temperatures higher or lower than 40 degrees Celsius fermentation is inhibited. Alcoholic fermentation is used in food production such as brewing, winemaking, and baking (Campbell). Thus optimizing fermentation and understanding the effect of various environmental factors can have important economic and social benefits. The production of CO2 is being assessed to show the rate of fermentation at certain…

Overall, I rate this article as a 4 out of 5. It is very well organized, presents samples and comparisons and is very well written. The only thing, I would change in this article would be the organization of the topics. For Example, The hypotheses, methods and procedures were placed at the end with the results. I believe the hypotheses, methods, and procedures would have been more effective placed at the beginning of the article before the presentation of the data that is broken up into sections…

Wind Direction’s Effect on Flour Beetle Search Behavior INTRODUCTION ϖ Background Beetles are arthropods and generally classified as insects (General Biology, 2014). The flour beetle (Tribolium spp.) is commonly found in flour mills, food storage warehouses, and even homes, where it feeds upon flour and other grains (General Biology, 2014). Though flour beetles are harmless, they are a huge agricultural problem (General Biology, 2014). Due to their status as an agricultural pest, it is…

The following equation 3.5, 3.6 and 3.7 used to compute Land surface Emissivity, mean of LST and change of LSE of Band 10 and 11, respectively. LSE=0.004Pv+0.986 Eq. (3.5) Mean of LST= (LST10+LST11)/2 Eq. (3.6) Difference of land surface emissivity (LSE) =LSE10-LSE11…

Similarity indices and genetic distance The overall mean similarity index for Brassica oleracea accessions calculated based on all AFLP fragments amplified using Nei’s (1978) similarity index, ranged from 0.297 to 0.999 with an average of 0.744 (Table 3). The highest similarity indices (0.999) and the lowest genetic distance (0.001) were between the accessions of the same crop variety and geographical region, e.g. spring cabbage HRIGRU4564 and HRIGRU4571 from Cork. Accessions having close…

The experiment consisted of numerous limitations and uncontrolled variables which impacted on the validity of the outcome. The lack of repetition was a major limitation in this experiment. The shortage of repetition forbids the elimination of outliers that may cause inaccuracy in the practical outcome. The lack of repetition in this experiment provided erroneous practical results where experimenters are mislead due to outliers, hence conclusions could not be accurately drawn. According to…

relies on measurement as a principal source of information [2]. In each quantified measurement, the obtained result is always uncertain. According to JCGM 200, measurement uncertainty is defined as follows: " non-negative parameter characterizing the dispersion of the quantity values being attributed to a measurand, based on the information used, according to the probability distribution function" [3]. No measurement result is quite accurate and reliable, unless it is reported with uncertainty…

In the Red Bead Experiment, a small proportion of red beads are interspersed with white beads. In this model, the white beads are desirable by the customer whereas the red beads are not and can be considered as errors. The employee receives instructions on how to collect the beads properly and proceeds to do so. The results are then tallied documenting the number of errors (red beads) which are identified. There are a number of interpretations of the data derived from this experiment…
