R u and @cynthiamex the same person? Bc they asked the same question..Marieniz wrote: ↑December 21st, 2019, 12:26 pm When i click on view first unread every 2nd time i get sent to a post somewhere in the middle of the thread leaving me having to go throught a load of posts i have already read not a problem cause i tend to pick things up that i have missed . just wondering if this happens to anyone else?
Cheers
I'm not sure if this is the format you want the answers in but here it is using a ball dropping experiment as an example:madhavaniyengar wrote: ↑January 4th, 2020, 10:54 pmyo anyone tryna answer this question? would very much appreciate it.

Observation about results: All of our results for this experiment reflected our predicted trend of rebound height increasing with drop height. Observation about procedure: The procedure required the ball to be dropped from greater than 0 cm a total of 9 times. Observation during experiment: We would sometimes need to readjust the meterstick used to measure the drop and rebound height if it tilted to the side. Also here's some questions:
1. Give an example of a possible experimental error.
2. Write a statement of problem for any experiment.
Both of those seem correct.madhavaniyengar wrote: ↑January 4th, 2020, 10:54 pm
Going along with the ball dropping experiment
1. One possible error could be the ball not bouncing straight up after hitting the ground and bouncing up slightly diagonally. Because it doesn't bounce straight up, the height that we measure will be lower than it would if the ball went perfectly straight.
2. How does the initial height that a bouncy ball is dropped from affect the height to which it rebounds after hitting the ground?
Here's my question I guess - Give an example of a CER for the outliers section of the analysis.

I'm not really sure how to write CER since I've never done it but here goes... We had no outliers in our experiment testing the rebound height of a ball. All of our trials for each level of the IV were within 4 cm of the mean and median, (0 cm variation for 0 cm drop height, 3 cm variation for 30 cm drop height, 2 cm variation for 60 cm drop height, and 4 cm variation for 90 cm drop height. Compared to the mean and median rebound heights for each level of the IV, the trials with the greatest variation for each level of the IV were not significant enough to be considered outliers. Here's another question: Find two controlled variables and one constant for this experiment.
I'm going to say that food coloring is being dissolved.
