Calculating Math Quartiles - Is That Right?

[DrWarezz]

Just checking ...


In an ordered set of data:

• The lower quartile, Q1 = 1/4(n+1)th term within the series;
• The median, Q2 = 1/2(n+1)th term within the series;
• The upper quartile, Q3 = 3/4(n+1)th term within the series;
• The interquartile, IQ = Q3 - Q1
• The semi-interquartile, SIQ = 1/2 * IQ

Is that right?
