Comparing Dot Plots

Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots plotted on a number line, representing the frequency of data points.

Front

How do you find the range of a data set?

Back

The range is found by subtracting the smallest value from the largest value in the data set.

Front

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

Back

If a dot plot is skewed to the left, it means that the majority of the data points are concentrated on the right side, with a few lower values on the left.

Front

What is the median of a data set?

Back

The median is the middle value when the data points are arranged in ascending order.

Front

How do you compare the spread of two data sets?

Back

You can compare the spread by looking at the range, interquartile range, or standard deviation of the data sets.

Front

What is a higher median indicative of in a data set?

Back

A higher median indicates that the central tendency of the data is greater, suggesting that most values are higher.

Front

What does a wider spread in a dot plot indicate?

Back

A wider spread indicates that the data points are more dispersed, showing greater variability in the data.

Front

How can you identify the mode in a dot plot?

Back

The mode is the value that appears most frequently in the data set, represented by the highest stack of dots.

Front

What is the significance of comparing medians?

Back

Comparing medians helps to understand the central tendency of different data sets, especially when they have different spreads.

Front

What does it mean if two data sets have the same median?

Back

If two data sets have the same median, it means that the central value is the same, but the spread or distribution may differ.
