Can a given characteristic only be measured one way?
What is no
100
process in which we ask a question, form a hypothesis, test this hypothesis in an experiment, and finally make a conclusion about our hypothesis based on our results.
What is Science/The Scientific Method
100
∑(Y-Z)²+4=?
What is 52
100
When each score doesn't actually represent an amount.
What is Nominal
100
The measure of central tendency that counts the repeated amounts in a data set
What is the Mode
200
Name three things that are easy to measure
What is Weight, blood pressure, physical things

For the science fair, Jimmy makes a volcano following instructions that he found on the internet. Would this be considered science?
What is No it would not, he simply followed instructions he found online, he didn't test anything new or go through any trial and error. At one point it may have been science, but in this scenario, it wasn't science.
200
(∑X)²+(∑Y)²-(∑Z)²=?
What is -187
200
When each score represents an actual amount, but there is no true zero.
What is interval
200
The measure of central tendency that finds the average of a data set
What is mean
300
The interval has no true _____
What is zero

Sarah loves baking, she finds a cook book in her kitchen, and decides to make some brownies using a recipe she found. She knows she has to be very careful to use the exact amounts of ingredients or else the chemical reactions won't work correctly when baking and the brownies will come out wrong and she'll have to try again. Is this science?
What is Even though this problem may seem like science because she has to follow instructions closely, and baking involves all kinds of chemical reactions, she was still following instructions, and thus it isn't considered science.
300
√∑(X-Z)²-17∕32=? *This should be all over 32 not just the 17
What is .41
300
A scale of measurement that is measured, put in order, and has a meaningful zero
What is Ordinal
300
The measure of central tendency that counts the middle number in a data set
What is median
400
NOIR Stands for
What is Nominal, Ordinal, Interval, Ratio
400
Sarah decides that the brownies she made following a cook book recipe were too dry for her taste. Because of this, she tries to find a way to make the brownies more moist. She tries many different things, knowing she'll have to compensate the other ingredients as well. She tries a few different things before settling on one where she slightly modifies the recipe from the book. Is this science?
What is This is considered science. Even though her basis was using a pre-determined recipe, she still went through different ideas and tested them out, and came to conclusions to decide if they worked.
400
(∑X+∑Y)²+172-8/3=?
What is 1069.33
400
If I wanted to measure the temperature in degrees, both Fahrenheit/Celsius, which scale of measurement would I be using
What is interval
400
You can find what measure of central tendency for ONLY an interval and ratio scale of measurement?
What is Mean
500
Process of defining the measurement of a phenomena that is not directly measurable
What is Operationalization
500
Becky conducts an experiment in which she tests how plants respond in growth to different kinds of music. She has one plant grow with no music, she has one listening to rock, one listening to rap, and one listening to classical. Other than the music everything about the plants are the same (the type of plant, amount of sunlight they get, how often they are watered, etc.) In this experiment, what is the dependent variable and what is the independent variable? What is the control group and what is the experimental group?
What is The independent variable is the kind of music the plant is listening to (or not listening to) and the dependent variable is how the plant grows. The Control group is the plant not listening to music, while the experimental group are the three listening to music.
