Understanding Data Set Concepts

Mr. Bell introduces key statistical concepts for a sixth-grade unit, covering statistical questions, frequency tables, outliers, and measures like mean, median, mode, and range. He explains numerical data, spread, symmetry, and measures of center. The video also covers data displays such as dot plots, box plots, and histograms, as well as quartiles, interquartile range, and skewed data. Students are instructed to document these terms in a Google Doc for future reference.

What is a statistical question?

• A question with a single answer

• A question that can be answered by collecting data with variability

• A question that has no answer

• A question that is always true

What does a frequency table display?

• The average of a data set

• The variability of data

• How often each outcome occurs in a sample

• The median of a data set

What is an outlier in a data set?

• A data point that is similar to others

• A data point that is distinctly separate from the rest

• The most common data point

• The average of the data set

How do you calculate the mean of a data set?

• By subtracting the smallest number from the largest

• By summing all numbers and dividing by the count

• By identifying the most frequent value

• By finding the middle value

What is the mode of a data set?

• The average of the data set

• The range of the data set

• The most frequently occurring number

• The middle value of the data set

How is the range of a data set determined?

• By identifying the most common number

• By calculating the median

• By finding the average

• By subtracting the smallest number from the largest

What does the term 'spread' refer to in statistics?

• The middle value of the data set

• The most common data point

• The variability of data points from the mean or median

• The average of the data set

What is a cluster in a data set?

• Data gathered around one particular value

• The range of the data set

• A single data point

• The average of the data set

What is a box plot used for?

• Calculating the mean

• Showing the five-number summary of a data set

• Identifying outliers

• Displaying the frequency of data

What does it mean if data is skewed to the right?

• The data is symmetrical

• There is a long tail on the right side

• The data is evenly distributed

• There is a long tail on the left side
