Results Yasumuro and Ikeda (2011) discovered statistically significant differences between the poor and enriched environments through exploratory behavior, various body patterns, and reactions to stimulus. The duration of exploratory behavior witnessed in the octopuses in the poor environment were notably less frequent than the standard or enriched environments, while the enriched environments displayed the most exploration of all three environments. Variations of exploratory behavior were seen…

data was recorded on the data sheet. By using this formula the all obtained data was converted to stomata per unit area. Results: After counting stomata and calculating stomatal density, the average, standard deviation, and standard error of the mean values for the young leaf and for the old leaf were determined. The average stomatal density of young leaf was 146.43 6.09 (stoma/mm2) and the standard deviation was 19.25. The average value for the old leaf was 115.31 6.81 (stoma/mm2) and the…

The calibration curves were linear for concentrations between 15-150 µg/mL. The linearity…

from the lowest to the highest score. The data is split into 5 groups, Group 1 and 5 containing the lowest-ranked and highest-ranked road handling scores, respectively. Group 1 2 3 4 5 Median 4.58 4.585 4.455 4.475 4.51 Mean 4.566 4.5775 4.477 4.437 4.46 The lower median and mean practicality values for Groups 3, 4 and 5, compared to Groups 1 and 2, suggests that cars with better road handling tended to be less practical, though the curvilinear relationship illustrated…

determine if the mean diameters of hyperparasatized galls and not hyperparasatized galls, and the mean diameters of the galls preyed upon by birds and not preyed upon by birds, were significantly different. A t-test was also used to determine whether the mean weights of hyperparasatized galls and not hyperparasatized galls, and the mean weights of the galls preyed upon by birds and not preyed upon by birds, were significantly different. If the p-value was less than 0.05, the means were…

The first part of the experiment required one to trace the light rays going through a converging and diverging lenses. By setting up the light source towards the end of the paper and placing the lenses about 5 cm in front of the light the focal distances were found to be 14 cm for the converging lens and -5.5cm for the diverging lens. These focal distances theoretically make since because the converging lens causes the light rays to combine in front of the lens making it positive and the…

from 9 5 down to 82. After four weeks of interventions the scores of the group dropped slightly for the stress levels and more significantly for the number of fights. After the intervention the mean for the fights was cut in half down to 6; while, the stress level of the group only dropped slightly to a mean of 83. After the intervention still no extreme gap in the number of fights or stress levels were notices, as the number of fights ranged from 7 to 3, with a stress level ranging from 92…

Kurtosis is a statistical measure used to describe the distribution of observed data around the mean. Descriptive statistics do not enable us to make conclusions beyond the data we have analysed or reach conclusions regarding any inference we might have made. Measures of variability are another important technique used in descriptive statistics. These…

For the Coach group and Supporter group, a 3-second mean hug duration is plausible since this value falls within the 95% confidence interval. Since it falls between the two limits, there is a 95% chance of the length hug occurring in each relationship group. Coach/Athlete: Lower limit= 3.77-2(.451)=2.87…

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…
