Study Guide 1.2 Flashcards
What is the difference between mass and volume
Volume is the amount of space an object takes up. Mass is how much matter in a object
What is the difference between weight and mass
Mass is the amount of matter in a object and weight is how heavy something is
How do you calculate the mean
Add up all you data and then divide by the amount of numbers you have
How to you calculate range
The biggest data you have minus the smallest data
How do you calculate median
You line all your data up from L to G and pick the number in the middle
What is the difference between qualitative and quantitative data
Quantitative uses numbers and Qualitative is the data’s characteristics
What is the standard unit for mass
Kilograms (Kg)
How do you find the volume on a graduated cylinder
Use the meniscus line
What is a independent variable
The thing that is being changed;/ manipulated in a experimant
What is a dependent variable
The thing that is getting measured in a experiment
Why is it important to have a control group
It is important to have a control group because if you have to many independent variables then you do not know what is changing the dependent variable
How do you write a proper hypothesis
The phenomenon/topic>(is due too, is caused by, depends on)<specific reason–if (independent variable) increases/decreases then the (dependent variable), will decrease/ increase
What is the difference between extrapolation and interpolation
To extrapolate is to infer something not explicitly stated from existing information. Interpolation is the act of estimating a value within two known values that exist within a sequence of values.
