Apparent weight is lessened by buoyancy, which occurs when an object is immersed in a fluid (a liquid or a gas). For example, an object immersed in water weighs less, according to a spring balance, than the same object in air. The apparent weight of a floating object is zero.

Yes, you do WEIGH less.
A person's apparent weight is less, yes. However, his/her mass is the SAME no matter where they are.
Mass is the same no matter where you are, but apparent-weight can change depending on conditions.
You might notice a difference of WEIGHT when at higher/lower altitudes and this is why.
Weight only depends on gravity's push against you. In water there is a less push and so you weigh less.

Yes, you are buoyed up (lightened) by an amount equal to the weight of the water you displace with your body. So if you weigh 150 lbs normally, and your body displaces say 15 gallons of water, which weighs about 120 lbs, then you would feel (like by the pressure on your feet as you stood on the bottom of the pool) as if you only weighed 30 lbs. If you displace more weight in water than you weigh, then you float! That's how metal ships can float.

Since I have never weighed anything underwater, but have weighed lots of stuff on land [stuff in science classes, stuff at the hardware store, stuff at the grocery store, etc], I would have to say yes since nothing is less than lots of somethings.
So, YES.

Since water is a lquid, and there is no gravity in lquid, YOU CAN NOT WEIGH A PERSON IN WATER.You can weigh mass, but that would me the same as your weight outside the water!

no you weigh the same, but in the water you feel like less

In water. It's a whole OTHER story when you come out of the water onto the land, though.:)

You have the same mass, but since water supports a larger portion of your mass, less force actually pushes down and you feel much lighter.

Your body mass is the same. Water is not a magical diet substance. You cannot loose weight by floating in water unless you plan to stay there your entire life.

you weigh the same but are bouyant in the water so feel like you weigh less.
