Ulnar deviation

set consist of 44 female and 53 males. b. There are 21 people under the age range of 13-35, which account for 21.6% of the total 97 in the sample. c. The mean level of the hour spent in the office during week 2 is 47.47 hours, with the standard deviation of 17.06. The distribution is slightly negative skew (-0.237), although in an acceptable range suggest that slightly more samples spend more hours in office than the average. The distribution’s value for kurtosis (-1.005) exceeds the acceptance…

important to shoppers. Ease of Return/Exchange Goods In the category of ease of returning or exchanging goods, the mean was 4.913, a mode of 7, a range of 6, and a standard deviation of 2.066. The mean for the category fell in the middle of all the other categories and…

A sample revealed three bags of 56, two bags of 57, one bag of 55, and two bags of 58. To test the hypothesis that the mean candies per bag is 56, how many degrees of freedom are there? * 8 * 9 * 7 * 1 Which of the following is most appropriately displayed with a frequency table? * What percentage of people prefer Hunt's brand ketchup * The home location of the most valuable customers * The relationship between gender and job performance *…

Losers with high interest neighborhoods. Population 4: Losers with low interest neighborhoods. All of the calculations for this test were done by hand. I started by identify the populations that would be compared. I calculated the mean and standard deviation of each population and then calculated the degree of freedom between groups and within groups, and the total. Next, I determined the critical value according to the F Distribution chart, then calculated the grand mean, total sum of squares,…

1. QUESTION: Class, what does the correlation coefficients of -1, +1, and 0 tells you about the relationship between the two variables? It depends on the method one uses, but the Pearson correlation coefficient is the most widely used. Values in the form of numbers show the direction and how strong the relationship is between two different variables. These can range from -1.00 up to +1.00. If it is positive it is a direct relationship. For example, if one increases the other will also increase…

should be a noticeable and systematic increase in the standard deviation based on an increase in size of the target circle, while the matching circle mean should stay close to the actual physical size of the target circle. In other words, it should be possible to see a progressive and regular increase in the standard deviation from a 10-, to a 30-, to a 50-pixel circle; and alternately, a systematic decrease in the standard deviation when moving in the opposite direction from 50- down to a…

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…

class, despite showing some variance in the measured value of starch digested, was overall quite consistent. The average values for tube 2 which was at 4°C and tube 3 at 24°C were 0.03 mg/mL and 0.24 mg/mL respectively. The corresponding standard deviation values for tube 2 and 3 were found to be 0.037 and 0.063 respectively. Finally the standard error for tube 2 was 0.012 and the standard error for tube 3 was 0.021. Following the second experiment that determined the concentration of starch…

A total of four hypotheses were examined using the following variables: feelings of tension and anxiety before and after watching a video in which a news story covered a student going to a college campus with the intent of harming people, perceived threat while watching the video, perceived threat while watching similar news coverages, the number of hours a day spent consuming news, and participant gender. First, to test the hypothesis that feelings of tension and anxiety will be higher after…
