Statistical Analysis of Colored Stones by Using Random Sampling

Statistical Analysis of Colored Stones by using ergodic Sampling Naomi Malary Lab Report 1 Ecology Lab 312 L-1 October 12, 2009 display Random Sampling, a method often characterd by ecologist involves an episodic component. In this method, all members of the population become an equal chance of world selected as part of the sample. The results involving random sampling passel be categorize as descriptive statistics and inferential statistics (Montague 2009). Descriptive statistics includes simplified calculations of a apt(p) sample and arrange this information into charts and graphs that are easy to contrast.Trying to relate conclusions that extend beyond the immediate entropy alone describes inferential statistics. To archive the results of sampling, qualitative and quantitative data is used. Quantitative data lack is heedful and identified on a numerical scale, whereas Qualitative data approximates data but does not measure characteristics, properties and etc. The purp ose of this experiment was to use statistical analysis to evaluate random sampling of seeminged gems (Montague 2009). go conducting this experiment, we came up with a few nugatory hypotheses.The first energy assumption is that all the opposes that have the same colouration weigh the same. The second vigor hypothesis is that there are more black lapidates than red or xanthous stones. Therefore the Blue stones leave behind be picked the mosr. Our final null hypothesis is that the stones of the same color have the same length and that they will not vary in size. Method Our team was given a box of one hundred and two red, blue, and colour stones. Team members A and B took turns choosing stones via random sampling, team member E recorded the color of the chosen stone.Team member C measured the weighting of the stone with a scale, and team member D measured the length of the stone using a vernier capiler. Team members A and B regulate(p) the stones back into the box, mixed it, and we then repeated the procedure. Three sample tempereds were interpreted . The first set I were the first 5 samples taken (n=5), set II consist of n=10, and set III consist of n=30. Results There appeared to be a small difference between stone color and their honest weight (Table1. and figures 1-3).Upon observation, you will see that the yellow stones were big than the blue stones, and the blue stones were larger then the red stones (Table2. and figure 2-3). It can also be noted that the only sample set to have red stones selected was in set III (Figure 3). additionally, figure7 shows that blue stones were picked in greater balance wheel than the yellow and red stones. Discussion I hypothesized that all stones that consider the same color weighs the same. According to table 2, all the stones of the same color do not share the same weight.Though the average seemed relatively the same, there still was a difference in the weight. Therefore, I must(prenominal) reject my nu ll hypothesis on account of this information. The second null hypothesis state that there are more blue stones than yellow or red stones, therefore more blue stones will be picked than any other stone. According to figure 7, the blue stones accounted for 44%, the yellow stones 38%, and the red stones 18%. Therefore I will not be rejecting my hypothesis on the basis that there were more blue stones present than any other color.The final null hypothesis stated that the stones of the same color have the same length. Table 2 and figures 5-7, accounted for the accompaniment that the yellow stones were usually the longest and the red stones the shortest. Based on this information, I will not be rejecting this null hypothesis.
