Data Analysis 5.9A, 5.9B, 5.9C

What is the y-axis in a graph?

• The horizontal line on a graph that represents the independent variable.

• The vertical line on a graph that typically represents the dependent variable.

• A line that connects the origin to the highest point on the graph.

• The line that represents the average value of the data points.

What is positive correlation?

• Positive correlation occurs when two variables increase or decrease together, meaning that as one variable goes up, the other does too.

• Positive correlation occurs when one variable increases while the other decreases.

• Positive correlation is when two variables are unrelated to each other.

• Positive correlation means that both variables remain constant over time.

What is the importance of labeling axes in a graph?

• It makes the graph look more professional.

• It helps viewers understand what each axis represents, making the data easier to interpret.

• It allows for more data to be displayed on the graph.

• It is not necessary if the data is simple.

What is a data point?

• A data point is a single piece of information represented in a graph or chart, often shown as a dot in a scatter plot.

• A data point is a collection of data that is analyzed to find trends.

• A data point is a type of software used for data analysis.

• A data point is a measurement taken over a period of time.

How can you determine the number of items in a data set?

• By counting the frequency of each item listed in a frequency table.

• By averaging the values in the data set.

• By finding the median of the data set.

• By identifying the mode of the data set.

How do you read a bar graph?

• Look at the color of each bar to determine the value it represents for each category.

• To read a bar graph, look at the height of each bar to determine the value it represents for each category.

• Count the number of bars to find the total value represented.

• Read the labels on the x-axis only to understand the data.

What is a scatter plot?

• A type of chart that displays data in a circular format.

• A graph that shows the relationship between two variables by displaying data points on a two-dimensional grid.

• A diagram that represents data using bars of different heights.

• A visual representation of data using lines to connect points.

What is a bar graph?

• A visual representation of data using bars of different heights to show the frequency or amount of each category.

• A type of graph that uses lines to connect data points.

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

• A method of displaying data in a table format.

What does an ordered pair represent in a scatter plot?

• An ordered pair represents a specific point on a scatter plot, where the first number is the value on the x-axis and the second number is the value on the y-axis.

• An ordered pair indicates the average of all points in the scatter plot.

• An ordered pair shows the relationship between two variables without specifying their values.

• An ordered pair is used to connect two points in a scatter plot.

What is a frequency table?

• A method to calculate the mean of a dataset.

• A way to organize data that shows how often each value occurs in a dataset.

• A graphical representation of data using bars.

• A technique to find the median of a dataset.
