Question 1 (i) Mean: ‘’The sum of a series of measurements (or numbers) divided by the number of those measurements.’’ (Open University,2015: S104 Exploring Science Glossary, Milton Keynes, The Open University). Scientific Notation: ‘’ A notation that represents any number by expressing it as a number that is equal to or greater than 1 but less than 10, multiplied by a simple power of ten where the index may be positive or negative. Thus, 1.30 × 103 is in scientific notation (because 1.30 is…
Discussion The T-test from the class supported our hypothesis by showing that Sulfuric Acid diffused significantly faster than phenol red at both temperatures (Fig 1). We can say that our hypothesis for experiment one is supported under certain conditions. The rest of the data in our charts supports our hypothesis as well. However it is not well supported. The rest of the test results were inconsistent with the null hypothesis. The error bars from the class data show a possible cause of…
whether or not the means differ significantly. From a t-test a null hypothesis can be determined. The null hypothesis for this study is the mean number of species found within the lawn and the prairie are the same, while the alternative hypothesis states that the mean number of species found within the lawn and the prairie are not equal. As determined by the p-value of 0.007434, for a two-tail t-test, one should reject the null hypothesis and accept…
However, even though this is the population from which a sample was taken for the research, it may be assumed that ultimately the goal of the study is to define the population as all workers in Taiwan, for purposes of extrapolation of the data. Additionally, only respondents holding a full-time job were selected for the analysis in order to highlight the potential effects of work/family conflict (Lu et al., 2011). Description of Data and Descriptive Statistics A wide variety of data was…
reject the null hypothesis that the mean of D3 is not significantly different than the mean of D1. Consequently, another two-sample Pooled t test was used to test the hypothesis that the mean delivery speed of deliveryman 4 (D4) is not significantly different from mean delivery speed of deliveryman 1 (D1) at a 5% level of significance and 39 degrees of freedom. There was sufficient statistical evidence at the 5% significance level (t=-5.436 and tcrit=-2.023) to reject the null hypothesis that…
neurological and psychological abnormalities in individuals living in various sociocultural environments. The tests comprised of pictures, words, and symbols that recorded short-term memory and cognitive function on participants. The alternative hypothesis of this study states that…
CHAPTER IV RESULTS AND DISCUSSION Table 1: Relationship between Achievement Motivation and Aggression among Inter Collegiate Hockey Players Variable N M SD df r Achievement Motivation 100 26.28 5.72 98 -0.09 Vs. Aggression 11.15 2.58 rtab (98) = 0.19 It is apparent from the table 1 that obtained value of correlation coefficient (-0.09) is less than the tabulated value of correlation coefficient (0.19). It means there is no significant relationship found between…

1. Measure the distance from the top of the third floor balcony to the first floor using a tape measurer. It should start from the top railing of the balcony to until it touches the floor. 2. Take a meter stick and place the front of the car at zero. Turn on the car and let it run until the front reaches the end of the meter stick. Make sure to use a timer to see how long it takes the car too travel that far. Divide the change in distance it travel by the time it took to find the velocity of…
