## Number of Rows - Intro to Descriptive Statistics

• 0:00 - 0:06
We could really group this data any way we want. In fact, we could only have two
• 0:06 - 0:11
rows, one for the number of students younger than 50 years old, and one for the
• 0:11 - 0:17
number greater, but we don't have to. We could even have one row for each age.
• 0:17 - 0:22
So here, we could have 10, 11, 12, and then we would count to see how many
• 0:22 - 0:28
students are aged 10, how many students are aged 11. But this is not the most
• 0:28 - 0:34
convenient way. That's because, the frequency would most likely be 1 for all of
• 0:34 - 0:40
them, maybe 2 for a few. So, instead of doing that, how about we choose an
• 0:40 - 0:46
interval for each row? For example, 0 to 19 and then 20 to 39, then we can count
• 0:46 - 0:53
how many students are between ages 0 and 19, between 20 and 39, etc. This is
• 0:53 - 0:59
called the interval or bin or bucket. For the most part, we'll either call it an
• 0:59 - 1:06
interval or the bin and in this case the bin size is 20. That's because it
• 1:06 - 1:07
includes 0.
