Biophysical Ecology Lab Report

b) (10 points) Based on your results in a), graph publishers on a bubble chart using the

To analyze the data, first enter the data into an Excel spreadsheet. Baseline followed by treatment data would be entered in one column on the spreadsheet in order by week. Using the Excel functions, calculate the mean and standard deviation of the baseline. For cutting, the mean was 10.75, and the standard deviation 1.5. For walking, the mean was .75, and the standard deviation .95. Next, calculate the upper boundary by adding the mean and standard deviation, and the lower boundary by subtracting

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

The lab uses the measurements of a wooden dowel in length and diameter to collect data in order to interpret data in report form. The data is used to produce statistical data and how to correctly present it. A ruler and micrometer were used to measure the dimensions. Spreadsheets are then constructed in order to generate standard deviation, mean, median, mode, frequency, as well as variation of length, diameter, volume, and cross sectional area of the

Present all relevant data in a data table below. Include an observations section for any observations you made during the lab. Make sure you note the data needs to be converted before graphing.

4. Calculate the following measures of central tendency for the set of cube measurement data. Show your work or explain your procedure for each.

5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?

8. When finished recording your numbers from the two trail experiments take the average of each trial and compare the final results.

Figure 1. The graph illustrates the mean observed heterozygosity of the three lakes. The error bars represent standard deviation.

9. Compare the 95% and 99% confidence intervals for the hours of sleep a student gets. Explain

2. Sort the data by Gen or Gen 1 (into males and females) and find the mean and standard deviation for each gender for the following variables: Use the descriptive stats function for one gender and the Fx functions (average and stdev) for the other.

7. Experiment: On the GRAPH tab, click Clear data. This time, try to vary your response times randomly as you take the test. Click Start and take the test.

The graph shows all of the trials and then the average so the first trial was Coca-Cola and it went from low to high and back to low. After that one it was Crush and that one went to low and then medium then medium again then low.Then after that it was Sprite and Sprite started low then medium the high and then went down a little.Then we did our calculations and got our average.

Based on the chart, the mean was calculated by adding up the sum of the list and divide 18, which the number of the total listed prices. The mean is 135,000, which mean the average of the listed price. Secondly, the median was calculated by listing the number in numerical order from lowest to highest and located the number in the middle 126,000. The median represents the middle number of the listed price. After calculating the median I located the minimum and maximum based the lowest and highest data, which are 48,000 and 338,000. These represent the range of the listed price. Lastly, I used the formula to get the
