E dition of Bilal Sciences Sci Mes P . Do not detach the root from the seed Table 1: Raw data for petri dis c o Each group Calculate the average for the treatment (in check for a quick way to calcule averages using Excel on page) Average length of the roots for the treatment 2.8 cm Average weight of the seeds for the treatment: Table 2: Master Data Table of average root lengths and seed weights. Each table was given a different IAA concentration (written on petri dish). Copy down the class results in the table below Average root length(cm) concentration LAA) Average seed weight (mg) an 10 Oba 222 10 2.410 30 20 olo F 3.99 Now that you have collected and analyzed your data, you may want to display the data using different types of praphs. Merwer you made any preliminary (an edotal) observations about this experien?

Answer 1

Answer) Below is the graph of Average root length (cm) and treatment (concentration IAA). It is a scatterplot graph with a trendline added to it. You can easily plot this graph using excel by selecting the values of Average root length (cm) and treatment (concentration IAA) and clicking on the insert option where many types of graph options are given. The trendline can be added by selecting the data point on the graph and right-clicking on it you can find the option of add trendline. The graph will look like this (X axis- concentration, Y axis- Average root length) (trendline is blue in color)-

Average root length (cm) 3.85 28 0.62 0 5 10 15 20 - 25 30

And the graph between the treatment (concentration IAA) and Average seed weight (mg) is given below (X axis- Concentration, Y axis- Average seed size), (trendline is blue in color)-

Average seed weight (mg) 10 15 20 25

Observation-

It is very clear from the experiment that IAA concentration impacts the root length. The root length increases with the increase in the concentration of IAA. It is evident from the graph also where the trendline is showing an increasing trend in the root length along with the increase in the IAA concentration.

In the case of seed weight also increasing trend can be observed with respect to the IAA concentration. The graph shows an increasing trend which depicts that with the increase in the IAA cocentration the weight of the seed also increases. However, there is a slight reduction in the seed weight at IAA concentration of 15, which may be caused by some experimental error.
