whats the explanation of Average Response Time vs Transactions per sec?

hello guys,

 

i know this may sound stupid but im just confused on this 2 terminologies.

is the Average response time is the "average" value/time for example 100 transactions whatever what it is that would be the Average from LoadRunner going to the application server.

while the transactions per sec is the "speed" or throughput per transaction LoadRunner going to the application server.

 

am i correct? if not kindly simplify =)

 

 

thanks in advance
