The curves which are more flat than the normal curve are called __________.Select one:a.Platykurticb.Mesokurticc.Leptolurticd.Nanokurtic

Break Down the Problem

1. Identify the characteristics of the normal curve.
2. Understand the definitions of the different terms provided in the options.

Relevant Concepts

1. Normal Curve: A symmetric, bell-shaped curve that describes the distribution of many types of data.
2. Kurtosis: A statistical measure that describes the shape of a distribution's tails in relation to its overall shape.
   • Platykurtic: Distributions that are flatter than the normal distribution (lower kurtosis).
   • Mesokurtic: Distributions that have the same kurtosis as the normal distribution.
   • Leptokurtic: Distributions that are taller and more peaked than the normal distribution (higher kurtosis).
   • Nanokurtic: Not widely recognized in statistical context, could imply a very flat distribution but is less standard.

Analysis and Detail

• Since the question asks for a term that describes curves 'more flat than the normal curve', the correct term from the options provided is Platykurtic. This highlights distributions that exhibit less peakedness than the normal distribution, indicating a lower degree of kurtosis.

Verify and Summarize

• The characteristics of your options confirm that Platykurtic is the correct answer.

Final Answer

a. Platykurtic
