What is a translation in geometry?

Back

A translation is a type of transformation that moves every point of a shape the same distance in a specified direction.

Front

How do you translate a triangle ABC to triangle A'B'C' if the translation is left two and up nine?

Back

You move each vertex of triangle ABC two units to the left and nine units up to find the corresponding vertices of triangle A'B'C'.

What is the mean in statistics?

Back

The mean is the average of a set of numbers, calculated by adding all the values together and dividing by the number of values.

Front

How does an outlier affect the mean?

Back

An outlier can significantly increase or decrease the mean, making it less representative of the data set.

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, using bars to show the frequency of data within certain intervals.

Front

What is the class interval in a histogram?

Back

The class interval is the range of values that each bar in a histogram represents.

Front

What is a bar graph?

Back

A bar graph is a chart that presents categorical data with rectangular bars, where the length of each bar is proportional to the value it represents.

Front

What is the mode in statistics?

Back

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

Front

What is the median in statistics?

Back

The median is the middle value of a data set when the numbers are arranged in order.

Front

How do you find the difference between two frequencies in a histogram?

Back

Subtract the frequency of one class interval from the frequency of another to find the difference.
