A bank 'xyz' wants to know about its popularity among the residents of a city 'ABC' on the basis of number of bank accounts each family has and the average monthly account balance of each person. Briefly describe the steps to be taken for collecting data and what results can be checked through processing of the collected data.
To determine the popularity of bank 'xyz' among residents of city 'ABC', the following steps need to be taken:
Data Collection Steps:
The bank needs to systematically collect and record data about the residents. The first step is to identify the target population, which includes all families residing in city 'ABC'. The bank should then gather data on two key parameters: number of bank accounts each family has and the average monthly account balance of each person. This data can be collected through surveys, bank records, or a census-like process where information is systematically recorded.
Data Processing:
Once the data is collected, it needs to be processed using appropriate statistical techniques. The bank can calculate measures like mean to find the average number of accounts per family and average monthly balance. Standard deviation can be used to understand the variation in account balances among residents. Mode can help identify the most common number of accounts families hold.
Results and Analysis:
Through processing, the bank can check several results. They can compare the number of accounts held by families with other banks to assess their market share. The average monthly balance can indicate the trust level and financial engagement of residents with the bank. By analyzing this data, the bank can identify patterns and hidden traits about their popularity. The processed information helps in making conclusions or decisions about their position in the market and planning strategies for improvement.
Conclusion:
The collected and processed data enables the bank to understand their standing among competitors and make informed decisions for growth.
Explanation
