Standard deviation

specific, it is a practical method to express the relative frequency of questionnaire responses. Mean is used to describe the central tendency of all data (Manikandan, 2011). The standard deviation is used in conjunction with mean. Specifically, the mean measures the center of the distribution, while the standard deviation measures the spread of the distribution (Baillie, 1992). By compared with mean, the results of SD will show how spreads out the numbers are. The correlation is a statistical…

information. Thus, the pixel values vary from 0 to 255. Small training areas of around 300 pixels were selected from different land cover types from these 3 channels and also from the texture channels. Statistical data like Mean, Median and Standard Deviation is calculated and based on that, following conclusions were made. Numbe r of pixels 310 56 56.63 13.61 14.00 89.00 0 15 mean value Channe l 1: 6 July Channe 310 44 45.41 12.45 9.00 74.00 0 15 l 2 :…

Another numerical question is µ1>µ2. µ1 is defined as the sample mean of Hispanic workers salaries and µ2 defined as the sample mean of Caucasian workers salaries. The Hispanic sample population is six workers from the “Wages and Wage Earners Data Set.” Learning Team B needs to consider whether or not the population is normal as the population size is less than 30. This also prohibits use of the Central Limit Theorem until the data set is proven normal. The wage of one worker being much…

3.12: Data Analysis process Overall, the objective of the research analysis is to try to answer the research questions formulated in Chapter 1. Accordingly, a conceptual framework and propositions have been developed from these questions, and justified in the literature review section. Therefore, the data analysis will be pursued to gather evidence pertaining to the several concepts identified. Quantitative data from the questiormaire survey will be analyzed by utilizing the Statistical…

being free from defects, deficiencies and significant variations is known as quality. Quality is a perceptual, conditional, and somewhat subjective attribute and may be understood Sigma is a Greek term .It is used in statistics to represent standard deviation from mean value, an indicator of the degree of variation in a set of a process. Sigma measures how far a given process deviates from perfection. Higher sigma capability, better performance. Six Sigma emerged as a natural evolution in…

09.07 Task 1—Normal Distribution Scores on a statewide standardized test are normally distributed with a mean of 12.89 and a standard deviation of 1.95. Certificates are given to students whose scores are in the top 2% of those who took the test. This means that they scored better than 98% of the other test takers. Marcus received his score of 13.7 on the exam and is wondering why he didn’t receive a certificate. Show all work to determine whether Marcus’ score was high enough to earn a…

was also the outliers in the graphs in which was the thirty seven and forty nine because that was the maximum amount that people declared that they went too which was not close to all the other points that were adjacently grouped together. The standard deviation for all these plots is 7.97 in which makes the interquartile rage be interpreted in the box plot, Q1 is 6 and Q3 is 13. Some of the interferences that can be drawn would be the Q3 because of the larger points, the Q3 is then more spread…

exhibit elevated inattention. Inattention. First grade teachers will rate students scoring below benchmark scores on the ADHD-IV Rating Scale and the Social, Academic, and Emotional Behavior Risk Screener (SAEBRS). Students who a score 1.0 standard deviations above the mean on the inattention subscale of the ADHD-IV Rating Scale will be included in the study. The SAEBRS will be used to determine if a brief universal behavior screener identifies the same children as the ADHD-IV Rating Scale.…

Table one shows that mean for gender and shorter memory recall, with the standard deviations displayed within brackets. From analysing to Row mean, it is clear to see that males had a slightly higher level M=7.76 SD = 2.09; to females M=7.63 SD= (2.55). Examining the column means shows that as the day progressed so does the column…

Imagery ability A pre-experiment questionnaire was administered to establish the participants’ imagery ability prior to the imagery intervention. Questions focused on how easy it is for the participant to image and the vividness of these images. For example, how easy is it for the participants to image staying positive after setbacks. This helped to control for potential confounding variables as research has shown imagery ability influences the effectiveness of imagery (Gregg, Hall, McGowan, &…
