Can anyone provide me with some statistics or graphs or evidence of how an better security system can increase the number of users for online banking? I need to show this in a form of visual data so graphs or statistics that I can use?

All I can suggest is that you go to websites such as investopedia.com and businessinsider.com and use their search features. If you don't find what you need in one search, then change your search words.

I went to businessinsider and searched for this:

To find statistics or evidence demonstrating how implementing a better security system can increase the number of users for online banking, you can follow these steps:

1. Start by conducting a literature review or searching for academic articles, industry reports, and case studies on the topic. Look for relevant studies that specifically investigate the relationship between improved security and increased adoption of online banking.

2. Utilize databases such as Google Scholar, JSTOR, or research portals provided by educational institutions and industry organizations to find scholarly articles or reports. Use relevant keywords such as "online banking security," "user adoption," "increased users," "statistics," and "graphs" to refine your search.

3. Once you have identified potential sources, review the abstracts or summaries to determine if they contain the type of data you are looking for. Pay attention to any statistics, graphs, or evidence that link enhanced security measures with higher user adoption rates.

4. Access the full texts of the selected articles or reports that appear to be relevant. Carefully read through the methodology and findings sections to identify any statistical data or graphical representations that can support your argument.

5. Extract the relevant statistical information, such as the increase in user numbers or the percentage of user growth, and any accompanying graphs, tables, or charts that depict the relationship between improved security and increased online banking usage.

6. Compile the gathered data and visualize it using appropriate graph types, such as bar graphs, line graphs, or pie charts. Ensure that the graphs clearly portray the relationship between improved security and increased user adoption.

7. If you have access to statistical software like Excel, SPSS, or Tableau, utilize these tools to create visually appealing and accurate graphs. Otherwise, use online graphing tools like Google Sheets, Plotly, or Infogram, which offer user-friendly interfaces to generate professional-looking graphs.

8. Cite the sources of the statistics or evidence properly in your project or presentation to ensure academic integrity and credibility.

Remember, the specific statistics and evidence you find will depend on the availability of research on this topic. It is important to critically evaluate the quality and relevance of the sources to ensure they meet your requirements.
