ANSWERS
1. claim 2. evidence 3. reasoning - answer ✔✔-what are the three components of a scientific argument
Numerical information that can be measured and has a unit of measurement. - answer ✔✔-What is
quantitative data?
Discrete (counted) and continuous (measured). - answer ✔✔-What are the two types of quantitative
data?
descriptive and based on observations involving the 5 senses - answer ✔✔-qualitative data
A quantity that can be changed - answer ✔✔-Variable
Does not change value - answer ✔✔-Constant
X axis - answer ✔✔-Dependent variable is what coordinate
Y axis - answer ✔✔-Independent variable is what coordinate
The number of occurrences a data point is found in a data set - answer ✔✔-Frequency
Tell you how often something happens compared to the total number of times it could have happened.
A proportion expressed as a decimal, percentage, or fraction. - answer ✔✔-Relative frequency
Lowest number in the data set - answer ✔✔-Minimum
, Highest number in the data set - answer ✔✔-Maximum
Middle number in the data set - answer ✔✔-Median
The value that occurs most frequently in a given data set. - answer ✔✔-Mode
The average. Calculated by adding all the numbers together, and dividing by how many numbers in the
set. Represented by Greek letter - answer ✔✔-Mean
A measure of how spread out a data is around its mean. It tells you how much, on average, data points
deviate from the central tendency (average) of data set - answer ✔✔-Standard deviation
When there is a little variation. For example, students scores cluster around the average with a few
outliers. - answer ✔✔-What is an example of a low standard deviation?
If the student scores are spread out over a wider range, some students scoring much higher or lower
than the average. A greater variation. - answer ✔✔-What is an example of a high standard deviation?
Take a data set and find the mean of the data set. Subtract the mean from each data point and square
the results. Calculate the variance by dividing sum of squares by sample size to get average standard
deviation. Square root the variance to get average distance from mean in original units. - answer ✔✔-
How do you calculate standard deviation?
(2+4+6+8+10) / 5 = 6
2-6, 4-6, 6-6, 8-6, 10-6
(2-6)^2=16, (4-6)^2=4, (6-6)^2=0, (8-6)^2=4, (10-6)^2=16
16+4+0+4+16=40
40 = sum of squares - answer ✔✔-What is the first step to finding standard deviation of this data set 2,
4, 6, 8, 10
Divide some of squares by sample size to get standard deviation
