This week in math my goals were to:
- Evaluate findings and form conclusions
- complete a statistical investigation by collecting, displaying and discussing data.
- determine appropriate variables and data collection methods.
- choose an appropriate data display.
- analyse a data sample.
- use a database (spreadsheet) to collect and organise data.
- collect and display time- series data.
We also talked about what the variables are my understanding for a variable is: Something in an experiment that changes so we can see the differences
For example we used: the exercises.
The variables in this experiment are
2 min walk
2 min star jumps
2 min sit ups
2 min sprint .
This is my graph -
This is my table -
|
Tim
|
Harry
|
Sarah
|
Ave for each exercise
|
2 Min Walk
|
148
|
150
|
160
|
153
|
2 Min Star Jump
|
186
|
172
|
192
|
183
|
2 Min Situp
|
198
|
158
|
162
|
173
|
2 Min Sprint
|
206
|
198
|
200
|
201
|
Ave for each person
|
185
|
170
|
179
|
|
Then we had to write three conclusions about the experiment mine are:
The graph above shows that the 2 min sprint makes the participants heart rate increase the most for example the average heart rate for that exercise is 201 .
The graph above show that the 2 min walk make the participants heart rate increase the lowest for example the average heart rate for that exercise is 153.
The graph above show that Tim has the highest heart rate over all of the exercise for example his average heart rate is 185 over all of the exercises.
Have you ever measured your heart rate?
