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?
