Sarula recently completed a compatibility "quiz" from one of her favorite magazines, and although she and her boyfriend have been dating for nearly two years, the "quiz" results suggested they are not compatible. luckily, riley, one of sarula's friends, is a student of psychology and suggested that the "quiz" may not be valid. what is her friend suggesting?

Sarula's friend is suggesting that the quiz may not actually measure compatibility

Validity refers to the extent to which a test or measure actually measures what it claims or sets out to measure. For a test to give an accurate result, it is important for the test to be valid. In this instance, the quiz  Sarula took from the magazine may not be valid, since it probably is not based on legitimate scientific research. The quiz might have assessed things that have nothing to do with relationship compatibility. 

Currently, as of february 2016, an american traveling in france would be by the exchange rate. the weakness of the euro and the strength of the us dollar means that items in france cost less to an american than they otherwise would. of course, if this trend reverses and the us dollar weakens and the euro strengthens, such as was happening in early 2008, an american traveling in france would have an adverse experience because items would cost relatively more.
