1-Variable Statistics: Target 1A

Front

What is the Interquartile Range (IQR)?

Back

The IQR is a measure of statistical dispersion, representing the range between the first quartile (Q1) and the third quartile (Q3) in a data set.

Front

How do you determine which data set has a greater spread?

Back

You can compare the IQRs of the data sets; the one with the larger IQR has a greater spread.

Front

What does a box plot represent?

Back

A box plot visually displays the distribution of a data set, showing the median, quartiles, and potential outliers.

Front

What is the median?

Back

The median is the middle value of a data set when it is ordered from least to greatest.

Front

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

Back

If data is skewed to the right, it means that there are a few high values that pull the mean to the right of the median.

Front

What is a measure of variability?

Back

A measure of variability indicates how spread out the values in a data set are, such as range, variance, or standard deviation.

Front

What is the mean?

Back

The mean is the average of all data values, calculated by dividing the sum of the values by the number of values.

Front

What does it mean for a class to be consistent in their scores?

Back

A class is considered consistent if their scores are close to each other, resulting in a smaller variability.

Front

What is the difference between the mean and median?

Back

The mean is the average of all values, while the median is the middle value when the data is ordered.

Front

What is a potential outlier in a data set?

Back

A potential outlier is a data point that is significantly different from the other values in the data set.
