A confounding variable is an extraneous variable that is related to your independent variable and might affect your dependent variable. In an ideal study, there will be no confounding variables.
For example, student accounts have a limit of $100 limit per day, while non-business accounts usually are limited to $500 withdrawals a day. For business accounts, the bank offers $1000 withdrawals in one day. Chase also offers customers a withdrawal limit of $1000 every 24 hours.
There is no minimum on the amount you can add to your account; however, there is a daily maximum you can add to your account. The maximum daily limit is $10,000 for Direct Deposit and $1,500 for cash loads, although certain third party money transfer services may have their own daily limits.
