Dot Plots
This graph uses dots to show the frequency of each data value.
What is a dot plot?
The smallest data value in a data set.
What is the minimum?
The average of all numbers in a set.
What is the mean?
A histogram with bars roughly the same height is called this type of distribution.
What is uniform?
Another word for “average.”
What is mean?
In a dot plot, each dot represents this.
What is one data value?
If a dot plot shows five dots above “7,” how many times does the number 7 occur?
What is 5 times
The five-number summary includes: minimum, Q1, median, Q3, and this.
What is the maximum?
The middle value when numbers are ordered from least to greatest.
What is the median?
A data distribution with one peak in the center looks like this shape.
What is bell-shaped?
The spread between the maximum and minimum values.
What is the range?
The number of data values divided by 2 finds this position.
What is the median position?
The tallest stack of dots on a dot plot represents this.
What is the mode?
The distance between Q3 and Q1 is called this.
What is the interquartile range (IQR)?
The most frequently occurring number in a data set.
What is the mode?
If the data tail stretches longer to the right, the distribution is called this.
What is skewed right?
The middle 50% of data lies inside this part of a box plot.
What is the box (between Q1 and Q3)?
Data set: 2, 3, 4, 4, 5. What is the mode?
What is 4?
A dot plot shows values ranging from 2 to 10. What is the range?
What is 8?
A box plot shows Q1 = 10, Q3 = 20. What percentage of the data lies between these values?
What is 50%?
A set of values: 3, 5, 7, 7, 10. What is the median?
What is 7?
In a symmetric distribution, these two measures of center are the same.
What are the mean and median?
The process of ordering data and splitting it into four equal parts.
What is finding quartiles?
Box plot values: min=12, Q1=18, median=20, Q3=25, max=30. What is the IQR?
What is 7?
If a dot plot shows 10 total dots, what does the sum of the frequencies equal?
What is the total number of data values (10)?
A five-number summary has min = 5, Q1 = 10, median = 15, Q3 = 20, max = 25. What is the range?
What is 20?
A data set has values 2, 4, 6, 8, 10. What is the mean?
What is 6?
A distribution with two peaks is called this
What is bimodal?
A graph showing data in intervals using bars with no spaces between them.
What is a histogram?
True or False: A box plot shows the mean of the data.
What is False?
