5: Conclusion

Did it support or reject your hypothesis?
From our calculations, there is a positive, very strong, and significant relationship between axilla & oral temperature.

The null hypothesis is rejected.

In addition to our findings, and with reference to the available literature that supports our hypothesis (Deepti Chaturvedi et al, "Comparison of Axillary Temperature with Rectal or Oral Temperature and Determination of Optimum Placement Time in Children", Indian Pediatrics, Vol. 41 (Jun 2004): 600 - 603), we can conclude that a person's oral temperature has a strong correlation to the axilla temperature.

4: Statistical Analysis & Results

Statistical analysis, correlation value, plots etc

Show the raw data




The images above are the data collected on Friday, 18th June 2010.
The 1st image is the details of each variable.
The 2nd image is the data collected.

Sex: sex of respondent
ot: oral temperature (degrees celcius)
at: axilla temperature (degrees celcius)
aot: average oral temperature (degrees celcius)
aat: average axilla temperature (degrees celcius)

Draw the necessary appropriate plots for the data values







The scatter plot and above data shows the following :

- There is a linear association between BP readings before and after exercise
- The Pearson’s R of 0.953 indicates a high positive relationship
- The Approx. Sig. Column indicates a p-value (0.000) of less than 0.05, suggesting that the relationship is significant.



From the table above, Pearson's r value is 0.953. This shows that there is a positive and strong relationship between oral and axilla temperature. The p value is 0.00, which is <>


Compute the value of the correlation coefficient

3: Methodology

How was the data collection done?
The data was collected at a air-conditioned area (Nanyang Polytechnic School of Health Sciences Blk J Room 204) over a period of 2 hours using the MedTecs VT-801BW Clinical Thermometer. Subjects were advised the day before to abstain from exercise for the 4 hours before the temperature taking.

How did you gather the samples?
The subjects were selected via a group of physiotherapy students via random selection of both genders ages 19 - 35.
A short questionnaire was presented prior to obtaining the temperature to ensure that they are not having any signs & symptoms of acute infections during the time of data collection or in the previous week. They were also briefed upon their privacy entitlement & that there would be no need for anonymity due to the unbiased nature of the experiment (a collection of data rather than an experiment of effect).

What did you use to measure?
To measure the oral temperature, subjects were seated while we inserted the thermometer into the oral cavity. The thermometer must be placed under the tongue. At any point in time the subject was not allowed to touch the thermometer. Same goes for the measurement of the axillary temperature but this time under the armpit. Recording of the data was done by another group member for efficiency.

Equipment
1. 2 MedTecs VT-801BW Clinical Thermometers (one for oral, another for axilla)
2. Alcohol swabs

The standardised way of placing the thermometer at the axilla

The thermometer was swabbed between subjects with the alcohol swabs available.

How often did we measure?
3 measurements were taken at the oral cavity & 3 measurements were taken at the axilla with the averages calculated for each component for data analysis in SPSS. This is to minimise discrepancies due to human or systemic error that might interfere with interference of the results.

Any rejection?
There was no rejection of data. The subjects also volunteered out of their own free will.
