Fast plant Experiment over 21 days, record height in cm on day 3, 7, 14, and 21.

Control= growing a plant using only regular water

experiment= using a 0.175% salt solution

Results:

Day 3 control= 1.2 cm 0.175%= 0 cm percent difference = -100%

Day 7 control= 5 cm 0.175%= 2.3 percent difference= -117.2

Day 14 control= 5.6 cm 0.175%= 3.3 cm percent difference= -69.69%

Day 21 control= 6.4 cm 0.175%= 3.9 cm percent difference= -64.1%

I need to make a scatter plot graph using this data. The bottom of the graph will be the days and the side values would be the height. They need to be a scatter plot showing the growth of each line and include the p-values. I will attach a picture as an example of what it should look like.

Log in to TheraNest N Registration - Noridi... Facility Login Infor... MyLab & Mastering BigBlueButton 11. Continue on and add a trendline for Data Set 2 and Data Set 3 following the same procedure. Make sure you are still on the Layout tab and click on Trendline. When the drop-down menu appears, click on More Trendline Options. Click on Data Set 2 and then click Ok. Make sure "Linear" is selected under the “Trend/Regression Type" and that “Display Equation on chart" is selected at the bottom. Then click Close. Click on Trendline a third time and click More Trendline Options. Then click on Data Set 3. Again, make sure "Linear" is selected under the "Trend/Regression Type" and that “Display Equation on chart" is selected at the bottom. Then click Close. Your graph should now look something like this... Descriptive Title Goes Here! Data Set 1 y = 0.3133x +0.4 R-0.96547 Data Set 2 Data Set 3 Linear (Data Set 1) Linear (Data Set 2) y = 0.2133x +0.6 R=0.98462 Linear (Data Set 3) y=0.0933x +1.6 R.O.S Time (minutes)

Answer 1

Okay, your plot is this one:

Plant growth across time with different water resources 8 y = 0.2472x + 1.7695 R2 = 0.7229 Growth (cm) 4. Y = 0.1977x +0.1503 R = 0.8361 O 0 5 10 15 20 25 Time (days) 0.175% salt solution Regular water Lineal (Regular water) Lineal (0.175% salt solution)

Excel is an excellent tool to make this graphs, you just have to insert the data and chose the right plot. A trend line with equation and R2 value can be added if you require it (like in this casef).

Note that your experimental treatment decreased plant growth compared to just regular water. Salinity ended up decreasing growth.
