Do you like squats? Well, in my class some people are really good. We did a data analysis project in groups and our project was based on squats.
Our inquiry question was. How many squats can you do in thirty seconds?
The equipment my group used was:
- A timer to to time the 30 seconds
- A pencil and a piece of paper to record the results
- Get the victim
- Start timer
- Count squats
- Record it
- Find the mean, median, mode, and range
Control standards are like rules to make the experiment or test fair. My groups control standards were:
- Squat with hands out in front of you
- Start with hands at side
- Down into sitting on tiny chair position
- Legs should length apart
Improper squats didn’t count.
My prediction was that the average would be about 25. The highest anyone would have gotten was 30. The lowest anyone would get is 20.
The number of squats the kids we recorded did were:
16, 20, 21, 22, 23, 24, 24, 24, 25, 25, 26, 26, 28, 28, 28, 29, 31, 33
Daniel got 33, come checkout his blog right here.
Analysis Of Our Data:
We had no outliers for this project. We were going to say that 16 was an outlier but then we decided to not say that they were one because there was only a four number difference. For mean, median, mode and range we got this:
Mean: 25.3 (What you do is add all the data points (numbers) in the data set then divide it by the number of data pints in the set. So the equation is: 16+20+21+22+23+24+24+24+25+25+26+26+28+28+28+29+31+33= 406÷17= 25.3)
Median: 25 (because 25 was the data point in the middle of our data set)
Mode: 25, 24 and 28 (Because that was the two most common data points in the data set.)
Range: 17 (how to get the range is you take the biggest data point then subtract the smallest into it so the equation is 33-16=17)
I think that the mean is the most appropriate measure to use because all of the numbers don’t have a big difference to each other.
This has been my data analysis project, comment below any concerns or questions.
