Research Project Data Collection 1,2,3 - Essay Example The number of ATM uses is presented as a bar chart as shown in Figures A.1, B.1, and C.1. A bar chart is, "†¦a way of summarising a set of categorical data. It is often used in exploratory data analysis to illustrate the major features of the distribution of the data in a convenient form.

These results were different from the theory that a debit card would lead to an increase in ATM transaction. However, Figures A.2, B.2, and C.2 show a strong positive correlation between the account balance and the number of ATM transactions as would be expected. This was true for all customers whether they had a debit card or not. Data could be collected through a variety of mechanisms that each have their strength and weaknesses. If the research
