We will try our best to operationalise our variables by tallying the cars for the same period of time and by collecting data in different locations throughout Maidstone. Our IV will be the gender and how dependent variable (DV) will be the size of the cars. To make it easier to see the driver or the car, we will be collecting our data by a set of traffic lights, and tallying in the correct sections.
Participants
All of our participants will be over 17, as this is the legal minimum driving age. We will be using opportunity sampling as only those driving at the time of the study will take part in the study.
Apparatus
Pen, paper and clipboard
Procedure
- A table was draw up to collect results in (a copy can be found in appendix)
- Researchers decided time and place of when they will be getting results
- Researches went to location, stood by the nearest traffic light and collect results
- Next lesson, the results were pooled
- Adjustments were made
- Carried out inertial test using chi-squared test
Control:
Pilot study was not to include family and sports cars as they are marketed differently and tend to be gender neutral. We increased our ecological validity by carrying out the experiment in different places in Maidstone.
Ethics
We followed most of the ethical guidelines by: ensuring that no participants were harmed physically or psychology and that the results were anonymous. Participants were not given fully-informed consent and were not debriefed as this would be too time consuming, but if a participant was to ask about our study they would have been told the true aim of the study and having their results omitted if they want to.
RESULTS
We will accept our null hypothesis and reject our alternative hypothesis because our observed value (1.34) of chi-squared is lower than the critical value(3.841) and this means our results aren’t significant. Therefore the probability of our results being due to chance equal p<0.5.
Evaluation
Our results are not generalisable because our participants are only form Maidstone and surroundings areas. People from different areas may have different cars and adverts in different cars might be marketed differently where males may not necessarily drive large cars and females drive small cars. To improve the study, we could look at adverts from other countries and if they are different, we could see whether they have an effect on the drivers.
By using opportunity sampling, our results were not representative because there might be different people that only drive specifically during a certain time of day.
Our results are not reliable as they have inter rater reliability and also it is likely that participants may not have been driving their own car – they might have been driving a family member’s car or a company car – either way they might have not necessarily been driving their own car. This means our results would be unreliable because we are trying to find out if advertising influences a person’s choice in cars – we would have to ask the participants if they are driving their own cars and discard the results of those who aren’t. However, this is would be too time consuming and the only way of doing this efficiently is to do it in a car park but this would mean our sample size would be small.
We can also tell that our results aren’t replicable as other members of our class had different results and did accept their alternative hypothesis (we all carried out the same tasks with the same aim but under different conditions) and they are not similar to the key study (Bandura) as his study would suggest that advertising would have an effect on people’s choice on the size of the car.
Also, there are other factors that may influence the choice on car, for example the cost of the car. Our results were made insignificant because there were more males driving small cars than large cars but overall there were more small cars than large cars observed in the experiment and this could be due to smaller cars being cheaper rather than the way they are being observed.
We could carry out the experiment at different types to have more control over extraneous variables in order to try and improve our study.
Seeing as our results show that there is no difference between gender and the size of the car, it seems that our study would have applications to real life as it shows that advertisers are wasting their money marketing their cars specifically to male/females.
The study was valid in that it was a naturalistic observation of real driving behaviour that was not affected by the observer. The drivers of the cars were either male or female. Also, our study has face validity as there are different opinions on types and the sizes of cars, even though there was a general outline, most of us did get confused about some cars and to those that we could not categorise were not included in the study.
Our study would be ethical regardless of the fact that informed consent was not given as if participants were to ask us about the study; they would be informed about the true aim.
