The formal definition for the mode of a dataset is:

The most frequently occurring observation in the dataset. A dataset can have multiple modes if there is more than one value with the same maximum frequency.

While you may be able to find the mode of a small dataset by simply looking through it, if you have trouble, we recommend you follow these two steps:

1. Find the frequency of every unique number in the dataset
2. Determine which number has the highest frequency

#### Example

Say we have a dataset with the following ten numbers:

$24,\ 16,\ 12,\ 10,\ 12,\ 28,\ 38,\ 12,\ 28,\ 24$

Let’s find the frequency of each number:

24 16 12 10 28 38
2 1 3 1 2 1

From the table, we can see that our mode is 12, the most frequent number in our dataset.

### Instructions

1.

Determine the mode of the ages for the first ten authors in the Le Monde survey:

$29, 49, 42, 43, 32, 38, 37, 41, 27, 27$

Save the value to mode_age.

2.

Determine the number of authors who were the age of the mode. Save the number to mode_count.
