Foundations
These are the four principal components of statistics, in order.
What are collect data, organize data, analyze data, and interpret data?
Favorite music genre is this type of data.
What is qualitative?
This graph is commonly used to display frequencies of qualitative categories.
What is a bar graph?
For 5, 6, 6, 7, 8, this is the mode.
What is 6?
If Q1=12 and Q3=20, this is the IQR.
What is 8?
A teacher surveys 8 of the 19 students in a class. The 8 students are this.
What is the sample?
Number of siblings is this type of quantitative data.
What is quantitative discrete?
This graph uses touching bars to display grouped quantitative data.
What is a histogram?
For 5, 6, 6, 7, 8, this is the median.
What is 6?
If Q1=12 and Q3=20, this is the upper outlier fence.
What is 32?
A teacher surveys all 19 students in a class. The 19 students are this.
What is the population?
Projectile flight time measured in seconds is this type of quantitative data.
What is quantitative continuous?
This graph preserves the original values while displaying the shape of a relatively small quantitative data set.
This graph preserves the original values while displaying the shape of a relatively small quantitative data set.
For 5, 6, 6, 7, 8, this is the mean.
What is 6.4?
For the ordered data 2, 4, 6, 8, 10, 12, 14, 16, 18, our class rule gives this value for the 60th percentile.
What is 13?
This symbol represents the mean of a sample.
What is x-bar?
A jersey number looks numerical, but when it only identifies a player, it is this rather than quantitative data.
What is a label?
This type of graph is especially useful for comparing the same qualitative categories across two groups.
What is a side-by-side bar graph?
A distribution has a long tail to the right. Name the shape and state which is generally larger, mean or median.
What is right-skewed, with mean greater than median?
A data set has mean 50 and standard deviation 5. A value of 60 has this z-score.
What is 2?
Give the meanings of all three symbols: n, sx, σ.
What are sample size, sample standard deviation, and population standard deviation?
A table that organizes two qualitative variables at once, such as grade level and lunch preference, is called this.
What is a two-way table?
A graph of quiz averages 96 and 98 begins its vertical axis at 94, making the difference look enormous. This is the misleading feature.
What is a truncated vertical axis?
For quantitative data with strong outliers or substantial skew, these are usually the preferred measures of center and spread.
What are median and IQR?
A value has a z-score of −1.5. Interpret that result in words.
What is 1.5 standard deviations below the mean?
