Question

Which of the following graphs would best display the data shown in the frequency table?

Age Tally Frequency
8 5
9 ||| 8
10 || 7
11 |||| 4
12 0
13 | 1
histogram
stem-and-leaf graph
dot plot

Answer 1

So you have
8 -> 5 times
9 -> 8 times
10 -> 7 times
11 -> 4 times
12 -> 0 times
13 -> 1 time

I think this one would be better answered in process of elimination
Stem and leaf plot - a stem and leaf plot is used where you have the tens value on the left, ones value on the left, as you can see, the numbers are only 8, 9, 10 , 11, 12, with only 3 of them even having a tens value

So do you think you would use a stem and leaf plot?

Answer 2

no

Answer 3

So now
well, you can search up 'when is a histogram/dot plot best used for'

for dot plot:
"Dot plots are used for continuous, quantitative, univariate data. Data points may be labelled if there are few of them. Dot plots are one of the simplest statistical plots, and are suitable for small to moderate sized data sets. They are useful for highlighting clusters and gaps, as well as outliers." - https://en.wikipedia.org/wiki/Dot_plot_(statistics)#:~:text=Dot%20plots%20are%20used%20for,gaps%2C%20as%20well%20as%20outliers.

for histogram:
"The histogram is used for variables whose values are numerical and measured on an interval scale. It is generally used when dealing with large data sets (greater than 100 observations). A histogram can also help detect any unusual observations (outliers) or any gaps in the data." - https://www150.statcan.gc.ca/n1/edu/power-pouvoir/ch9/histo/5214822-eng.htm#:~:text=The%20histogram%20is%20used%20for,any%20gaps%20in%20the%20data.

So which one do you think that you'll use for this data set

Answer 4

I think it would be dot plots

Answer 5

yeee i think that too xd

Answer 6

okay thank you so much
