Standard deviation

The mean maladaptive perfectionism scores are average and the low standard deviation shows that there was little variation between student’s maladaptive perfectionism scores. A correlation coefficient was calculated between procrastination and adaptive perfectionism scores (r (523) = -.14, p < .001). A significant negative correlation…

review of experimental evaluations of PD programs in developed countries, Yoon et al. (2007) found that the academic achievement of students whose teachers participated in PD programs (about 49 hours of training on average) increased by 0.54 standard deviations compared to students whose teachers did not participate in PD. These positive findings lend credence to the efforts of policymakers from developing countries who are in favor of using PD to improve the quality of teaching in their rural…

numeric, continuous variable therefore a dot plot and a box plot are used. The modality of the data is unimodal (one peak) at 339 minutes. 50% of the Ironman athletes finish the race between 305.6 and 370.7 minutes. Although, there is a large standard deviation of 48.9. This entails that there is a large distance between the mean and the points, hence a…

RESULT & OBSERVATION The hypothesis for statistical testing must be written as Null hypothesis (H0) and Alternate (Research) hypothesis (H1) form. H0 1= There is no significant relationship between body height, foot length and knee height in both the sexes. H1 1= There is relationship between body height, foot length and knee height and are significant in both the sexes. H0 2= Body height is equally…

In this project, I will analyze the problem of gender inequality in terms of labor income. This problem is important in our society because people with same background and same experience should be treated the same in the same working environment. Women should not be judged based on their biological gender. The data sample used in this project is working individuals between ages 25 and 54 from Current Population Survey, 2012. Sample size contains 999 observations. I will first discuss the…

The experiment began with a reaction of a 1cm3 cube of lamb liver and 5mL of hydrogen peroxide solution being put in test tubes in a beaker filled with 10℃ water until the temperatures of the liver and hydrogen peroxide were 10℃ also. The liver was put into a 100mL measuring cylinder and the hydrogen peroxide was also poured in as the timer was started. After twenty seconds, several millilitres of froth had been produced from the chemical concoction. This froth was recorded into a results table,…

Life after High School This investigation was to find the change in future aspiration of high school seniors in the US after 9/11. The suggestion was that the economic impact of the attack would cause fewer childten to have the means to enroll in college. However some where divided on the impact it would have on enlistment as wether it would increase due to patriotistic sentiment or decrease with them rise in probability of actual engagement. An unidentified polling organization arranged…

The preeminent design of the paper helicopter experiment would comprise of the best mean and standard deviation of the overall measured data. An in depth comparison of the mean value and the standard deviation of each variable will be discussed in relation to a measure suitable for a longer flight time and a more accurate landing. These variables will be discussed relevant to the data and information gathered from our experiment during testing. The ratio of each helicopter will be discussed in…

F-test for the two conditions equaled 4.61, with a p value of less than .05. The average for that conditions was 7.5 pixels with a standard error of 0.47. The average for the other-name condition was 6.8 pixels, with a standard error of 0.41. Although there was a greater difference between the rightward deviations for the two conditions than the leftward deviations, it was not significant according to the t-test (t(16)= -1.03, p=.32, two-tailed. The researchers then went on to discount the…
