### 3 Statements

Maybe instruments were expensive in 2001 Because not many kids did orchestra.

In 2007 The cost of instruments might have been low, since so many kids played in the orchestra.

Another reason not many kids did orchestra in 2001 may be because it just started.

### Outliers

An outlier is 22. it may affect the data because some kids may think Orchestra isn't fun since so little kids did it.

### Information

22,31,35,47,39,55,66,60,62,56

### Mean, Median, Mode, and Range

Mean: 47 Remainder 3

Median: 51

Mode: None

Range: 44

The explanation.

### Mean

I added all the data and got 473.

You divide it by 10 because There's 10 pieces of information.

And 473 divided by 10= 47 r3.

### Median

I listed all the numbers in order then crossed off the bottom then top numbers and got 47 and 55.

Then I counted down from 55 and up from 47.

They met at 51.

### Mode

No two numbers match.

### Range

I took the highest number and the lowest number, 22 and 66, then subtracted them.

I got 44.

### Changes In The Data

If one kid didn’t like band, and he transferred to orchestra, That would change the data.

### THE END

Thanks for watching.
