For a bathroom scale to be reliable it means there is consistency which means it gives the same value each time an object or a person is placed on it but the reason why it is not valid is that it is giving an inaccurate/ incorrect value.
No, because for a scale to be valid it means that it must be accurate but the validity and reliability work hand in hand because for a scale to be valid it has to be consistent. It would have to show the correct weight and for it to be reliable it would have to be showing the same value.
First of all external Validity means outside the laboratory and internal validity means inside the laboratory but what it means for something to have good validity but lack external validity because most times something can work inside the laboratory but may not work outside in the sense that an experiment inside the laboratory can yield accurate result which is it having good internal validity but can lack external validity because in the laboratory the variables can be manipulated while in the outside world it cannot.
For me, the best method for jealousy would be the use of the survey because then you would be gathering more information about the different opinions from the individuals participating in the survey because you would have to make it consistent by asking the same questions in the survey but due to the different answers there would probably be some accurate information.
