Find modes of Data Set
\[
4,5,4,4,7,3,5,7,3,7,6,7,5,45
\]
If there is more than one mode, Write them seperated by comas, If there is no mode, click on no mode

Step 1 ：Given the data set [4, 5, 4, 4, 7, 3, 5, 7, 3, 7, 6, 7, 5, 45], we need to find the mode. The mode is the number that appears most frequently in the data set.

Step 2 ：First, we create a frequency distribution, which is a list of the data values along with their corresponding frequencies (the number of times each value appears in the data set).

Step 3 ：The frequency distribution for this data set is {7: 4, 4: 3, 5: 3, 3: 2, 6: 1, 45: 1}.

Step 4 ：From the frequency distribution, we can see that the number 7 appears most frequently, with a frequency of 4.

Step 5 ：Therefore, the mode of the data set is 7.
