What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, showing the frequency of data points within specified ranges (bins).

How do you find the median of a data set?

Back

To find the median, arrange the data points in ascending order and identify the middle value. If there is an even number of data points, the median is the average of the two middle values.

Front

What does it mean if a dot plot is symmetrical?

Back

A symmetrical dot plot means that the data is evenly distributed around the center, with similar frequencies on both sides.

Front

What does it mean if a dot plot is skewed left?

Back

A left-skewed dot plot indicates that the majority of the data points are concentrated on the right side, with a tail extending to the left.

Front

What does it mean if a dot plot is skewed right?

Back

A right-skewed dot plot indicates that the majority of the data points are concentrated on the left side, with a tail extending to the right.

Front

How do you determine the mode of a data set?

Back

The mode is the value that appears most frequently in a data set.

Front

What is the range of a data set?

Back

The range is the difference between the highest and lowest values in a data set.

Front

What is a frequency distribution?

Back

A frequency distribution is a summary of how often each value occurs in a data set.

Front

How can you interpret a histogram?

Back

You can interpret a histogram by analyzing the height of the bars, which represents the frequency of data points within each bin.
