Explain how the order in which we are born can influence our personalities.

I’m going to use three children as my example to make it easier.

The oldest child will most likely be a good leader, having younger siblings to take care of. They also might be a bit bossy because younger sibling often listen to the older ones. Being the oldest they might also be more responsible, because parents might expect more of them because they are older.

The middle child is often a good peacemaker, being in the middle of the oldest and youngest. This could also help them be more generous. It’s possible the middle child will feel ignored, because the oldest child was first and the youngest was last.

The youngest child might like to be noticed with two older siblings so they might like to be the center of attention. Having older siblings can also make a child more competitive, and because they are around more people be more outgoing.

And also-
An only child might be more mature than a child with siblings because an only child would spend a lot of time with their parents. They might also be private and sensitive, not having siblings around to tease them.

Were is the question

You should never redesign your experiment. try and see what in your experiment you made a mistake on or try and test your experimemt with somebody else. see if they get the right results.
