Answer:
line graph
Explanation:
The explanations of each plot are:
Scatter plot
It is used to see the correlation between two variables. The correlation can be positive (increases), negative (decreases) or zero (no correlation at all). This plot can be used to draw a trend line to study the correlation between variables using an equation, generally a line and which prosses is call line regression.
Line graph
Is like the scatter plot but instead of leaving the data or points without connection the line graph connects the points, representing the data, with a line, so to easily show a tendency between variables, which generally tends to increase.
This plot is an easy way to show a tendency, but the scatter plot can give more statistical information about a correlation between variables.
box-and-whisker plot
Shows the median and the quartiles of the data, i.e. shows a interval in which the recollected data can be found and its frequency of repetition.
stem-and-leaf plot
Allows to simultaneously see the frequency distribution of the variable and its graphic representation and its constructed by separating, in each data, the last digit of the right (the leaf) to the remaining digits (the Stem).
So, to easily show numerical data in ascending order it can be used the line graph, but it can be used de scatter plot to give deeper statistical information too.
