Arithmetic mean

Problem: Apparatus 1: what is the relationship between height of release and the initial velocity? Apparatus 2: What is the relationship between length of the ball catcher and the final velocity of the system? Additional question: What is the percentage error of the initial velocity calculated using momentum and kinematics? Percentage error between theoretical initial velocity and experimental initial velocity? How much energy is lost? note: the initial velocity calculated using kinematics…

In the pre-test and post-test, the researchers looked at the mean scores of the tests. The test was based on a points system out of 100. For the more-proficient students, they received a mean score of 78.84 on the pre-test to 80.98 on the post-test. This does not show a significant change. For the less-proficient students they received a mean score of 62.75 on the pre-test to a 75.82 on the post-test (Yang and Meng, 2013, p.226). This shows much more…

The 12-lead ECG gives reading from 1 different electrical placements around the heart. The way that this works is each of the 12 signals are supposed to identify electrical activity from the heart's muscle. This however is not easy, it will take dedication and long hours before you are able to interpret the 12-lead ECG, but once done correctly you will be able to read these signals and therefore translate them. When approaching the 12 lead ECG, there are a few things that you must know. The last…

The details of the scores for each of the six factors analyzed in the NASA-TLX questionnaire (Fig. 3) reveal that the use of the robot impacts mostly on the mental demand of the task and on the effort required from the caregiver, while actually the use of the robot increases the temporal demands of the tasks. B. Division of the Caregivers Time Regarding the time spent with personalized attention to users, a total of 862 segments were annotated by the two annotators. Their annotation were in…

To assess the overall model fit of the measurement model, confirmatory factor analysis (CFA) was performed. The measurement properties resulted from CFA are summarized in Table 3. In this study, the chi-square statistic indicated the overall model was not fit very well (x^2 = 527.397, p < .001). However, The value of the normed chi-square static to sample size, showed that the model fit the data well with x^2/df at 2.028, which was lower than the recommended threshold of 3. In addition, the…

The Haybaler Problem Problem Statement You have five bales of hay. All of the bales of hay were weighed in combinations. 1 and 2, 1 and 3, etc.. All of the weights were written down without keeping track. The weights of the bales are 80,82,83,84,85,86,87,88,90, and 91. Your initial task is to find out how much each bale weights. Is your answer the only possible set of weights? Explain how you know. Process In the hay baler problem we had to figure out different combinations of weights of hay…

is N, neutral mutation fixation time t is equal to 4N generations and a mutation with a selective advantage of s takes (2/s)ln(2N) generations to become fixed. For a mutant with a selective disadvantage, there is a low fixation probability, which means that if the mutant is to become fixed the fixation time must be much faster than neutral mutant. Selective advantage mutants behave similar to adverse mutations because the mutation is either quickly lost or quickly fixed. Additionally, the…

room. The mean duration of tantrums with self-injurious behavior during baseline A1 for the group activity was 15.4 minutes (range 4-35 minutes). The mean duration of tantrums with self-injurious behavior during baseline A2 for the group activity was 17.75 minutes (range 3-30 minutes). With the implementation of vibrating stimulation and wrist weights, the mean duration of tantrums with self-injurious behavior, decreased to 10.75 minutes in intervention B1 (range 8-14 minutes). The mean duration…

In relation to the first question, the results showed that subjects in the control group rated their experience somewhat negatively. Subjects in the one dollar category rated their experience statistically more positively in comparison to the control group while the twenty dollar category’s average rating was only minimally higher than that of the control group. Participants in the one dollar group also responded more positively when asked about their willingness to participate it similar…
