- Q1What does a scatter plot show?the frequency of an eventthe total sum of valuesthe relationship between two variablesthe average of a set of numbers30s
- Q2Which of the following best describes a positive correlation in a scatter plot?There is no discernible pattern between the variables.As one variable increases, the other variable decreases.As one variable increases, the other variable also increases.Both variables remain constant.30s
- Q3In a scatter plot, what does each point represent?A predicted outcome based on the dataAn individual data point with values for two variables.A line connecting two variablesThe average of all the data points30s
- Q4What might a scatter plot with no clear pattern indicate about the relationship between two variables?Both variables are identical.There is a strong negative correlation.There is a strong positive correlation.There is no significant correlation between the variables.30s
- Q5What is the purpose of adding a line of best fit to a scatter plot?To show the exact values of all pointsTo change the scale of the axesTo indicate how many points there areTo summarize the trend of the data points.30s
- Q6How can outliers be identified in a scatter plot?By looking for points that lie directly on the line of best fit.By finding points that form a perfect line with other points.By spotting points that are far away from the general cluster of data points.By counting the number of points in the plot.30s
- Q7What could a scatter plot with a downward slope suggest about two variables?Both variables increase together.Both variables are constant.There is no relationship between the variables.As one variable increases, the other variable decreases.30s
- Q8What does it mean if a scatter plot shows a cloud of points with no discernible direction?The variables have a strong positive correlation.The variables have a strong negative correlation.There is likely no correlation between the variables.The variables are identical.30s
- Q9What does the x-axis typically represent in a scatter plot?The dependent variable onlyThe average of the valuesThe total number of data pointsOne of the variables being analyzed.30s
- Q10Why might a scientist use a scatter plot to present data?To visualize the relationship between two quantitative variables.To list all individual data valuesTo sort data into categoriesTo show the cumulative frequency30s
- Q11What does the trend line in a scatter plot represent?The minimum value in the data setThe average of all data pointsThe exact value of each data pointThe general direction or pattern of the data points30s
