Data Displays

What is the purpose of data displays?

• To visually represent data for easier understanding and analysis.

• To store data in a database for future use.

• To encrypt data for security purposes.

• To generate random data for testing.

What is the mode of a set of scores?

• The average of the scores in the set.

• The value that appears most frequently in a data set.

• The highest score in the set.

• The lowest score in the set.

What is a scatter plot?

• A type of graph that uses bars to represent data values.

• A graph that uses dots to represent the values obtained for two different variables - one plotted along the x-axis and the other along the y-axis.

• A circular chart divided into sectors to illustrate numerical proportions.

• A line graph that shows trends over time.

What type of Data Display uses bars to represent data?

• Bar Graph

• Line Graph

• Pie Chart

• Scatter Plot

What is the difference between a histogram and a bar graph?

• A histogram displays the frequency of numerical data in intervals, while a bar graph represents categorical data.

• A histogram is used for displaying categorical data, while a bar graph shows numerical data.

• A histogram uses bars of equal width, while a bar graph uses bars of varying widths.

• A histogram represents data over time, while a bar graph shows data at a single point in time.

What is a box plot?

• A graphical representation of data using bars to show frequency.

• A standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile, median, third quartile, and maximum.

• A method for calculating the mean of a dataset.

• A type of chart that shows the relationship between two variables.

What is a stem-and-leaf plot?

• A method of displaying qualitative data in a tabular format.

• A method of displaying quantitative data in a graphical format, similar to a histogram, to retain the original data values.

• A type of chart used for categorical data representation.

• A graphical representation of data that only shows the mean and median.

What is the range of a data set?

• The average of all values in the data set.

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

• The sum of all values in the data set divided by the number of values.

• The value that appears most frequently in the data set.

What type of Data Display shows the distribution of data over a continuous interval?

• Bar Chart

• Pie Chart

• Histogram

• Line Graph

What does a dot plot represent?

• A method of displaying data where each data point is represented by a dot above a number line.

• A type of graph that shows the frequency of data points in a dataset.

• A visual representation of data using bars to show quantities.

• A chart that uses lines to connect data points over time.
