 * How to Describe Data**
 * Data Type || Central or Typical Value ||  ||
 * Quantitative Data (based on measurement) || MEAN- arithmetic average || RANGE- difference between the minimum and maximum. ||
 * Qualitative Data (based on observations: color, relative size, etc.) || MODE- the most frequently occurring value || FREQUENCY DISTRIBUTION- the number of cases that fall into each category ||

[] (tutorial-Stem) Good for small data sets with one variable. Ideal for two digit data in a moderate range [] (tutorial-Box) Good for large sets of data. Greater than 10. You could also do scatterplots: [] Used for relationship between IV and DV any number of data points. IV plotted on x-axis, dependant variable y-axis. The best fit line goes on the graph showing the general relationship of the variables. The best fit is either a line or a parabola. Goes up or down. And sometimes, there is no pattern at all. [] [] The best site is below. Making Graph Software Do the tutorial for help with graphs.** []
 * Graphs are visual representations of data. They help you and the viewer see patterns that numbers in a table do not. Two quick graphical representations are Stem and Leaf Plots, and Box and Whiskers.**
 * Of course there are also line graphs, bar graphs, and pie charts. But when do you use which one?**
 * Line graph is good for small to medium sized sets of data with one variable. With larger than 20 sets of data, a histogram may be better. It is also preferable for continuous variables such as time. Discrete sets of data, like color and shape are better for bar graphs.**
 * Bar graph is a histogram. It is best for data that is qualitative in nature and/or greater than 20 data sets.**

The Analysis Writing an Analysis for Experiment
 * Step || Task || Example ||
 * 1. || What was the purpose of the experiment? What was the research hypothesis? || The purpose of this experiment was to investigate the effect of various fertilizers; Miracle Grow, Shultz, and manure on Chili Pepper plants (//Capsicum)//. It is believed that if you tested all three fertilizers on the same plants that the Miracle Grow plants would grow the fastest and be the most healthy. ||
 * 2. || What were the major findings? || The mean growth rate of the plants in the Manure Group was the greatest at 2.4 cm/week. The Miracle Grow did have a plant that was the maximum of 3.5cm/week. All three fertilizers were greater than the control. The manure produced the healthiest looking plants with .4 of the plants a robust green rating. ||
 * 3. || Was the research hypothesis supported/not supported? || In general, the data did not support the hypothesis that Miracle Grow would be the healthiest plants, because the manure plants grew the fastest and looked the best. ||
 * 4. || How did your research compare with your background research findings? || However, Cook and Baldwin found in their 2006 study that Miracle Grow performed the best out of all artificial fertilizers. The difference may be because Cook and Baldwin did not use natural fertilizers in their study. We did not find any other studies that worked with manure, therefore this study could be valuable. Manure does have excellent properties as mentioned in the US Dept. of Agriculture study, for pepper plants. ||
 * 5. || List possible factors that would lead to error. || The results could also be effected by unequal mixing of the fertilizers in the soil as this was difficult to determine. ||
 * 5. || What recommendations do you have for further studies? || Additional studies could be conducted to see if the results hold true with a variety of different species of garden plants. Perhaps //Capsicum// is the only plant that prefers manure? It is believed that a majority of garden vegetables would prefer manure over synthetics. Further research in this area is urged, as environmental issues have risen over the last 20 years regarding us of synthetic fertilizers for industrial agricultural practices. Clear evidence of the benefits of manure may sway practices to a more sustainable model. ||
