Proportion of Oswego residents that view banks in a negative manner.
Mail   Print   Twitter   Facebook

For this Project I chose to find the proportion of Oswego residents that have a negative or positive view of the Banking Industry.

Email link:

I generated a paper survey that was given to customers and returned to bank staff within their visit.  I collected the data weekly and submitted their answers through the online survey form.  A total of 53 surveys were collected.  The survey questions were as follows:

1. Do you currently have a banking relationship?  Yes or No

2. Age group? 18-45 or 46-65

3. What services do you use with your bank? ex.(checking, savings, mortgage, credit cards) 

4. What was your view of banks before 2007?  Positive or Negative

5. What is your view of banks post 2007? Positive or Negative

6. Do you trust banks today?  Yes or No


My Hypothesis Conjecture statement was that more than 65% of Oswego residents have a negative view of banking today.

Here is the data collected from survey participants and compiled by StatCrunch.

The pie chart below represents people with Bank Relationships as asked in question 1.  As you can see a overwhelming majority of people, 98% do have service with a bank. (Nominal)

Yes 52 0.9811321

 The next pie chart below represents the age of customers as asked in question 2.  The age groups were derived from banking statistics that reflect two major areas within a persons financial lifetime. Almost 68% were between 18 and 45. (Ordinal)

Sample Proportion = 38 / 53 = .716

Standard Deviation = 0.72(1-0.72)/53 = 0.617.

Hypothesis Test:

1.  Null Hypothesis and Alternative Hypothesis

      Ho = 0.65 and Ha < 0.65

2.  This is a left tailed test.

3.  Z score = √0.72(1-.072) / 53 = .617

     (0.716-0.65) = -0.066 / 0.617 =-.1069

4.  P score -.1069 rounded up to -0.11 which corresponds to 0.4562

5.  Reject or accept

Since P = .4562 and is greater than .05, we accept the null hypothesis that negative banking sentiment in Oswego is 65%. We have evidence to it.


The process of collecting data was given to bank staff at a local Oswego branch.  3 Tellers were given 30 paper based surveys for a total of 90, only 53 were completed and returned to me.  The other 37 surveys were also returned because they were not used, no surveys were incomplete.  I decided to go this route after very little response online. I decided to omit question 3 because it was not setup correctly within StatCrunch.  The year 2007 was used because of the market collapse time frame. Question 6 was based on the fact that the view is more related to bailouts and the fees that banks charge and comfort level of FDIC insurance rather than the real estate market and unemployment.  Most of the data collected is qualatative nominal.  Based on personal interaction with customers, I felt that negative sentiment was high in the area.  After collecting and compiling data my results were actually less than what I thought but still higher than my conjecture.  I have been in the financial industry for 10 years and sentiment has not been this negative in general but it seems worse in areas that have been hit the hardest by depreciation in real estate.
