Thank you so much. How about 50 random decimal values between 1.00 to 93.00?

The rand function creates random numbers from 0 to 1. See the documentation for more on specifying how many random numbers to create.

For your range, first create random numbers from 0-92 by multiplying the result by 92, then get it to go from 1-93 by adding 1.

r=rand(1,50)*92+1

r = 1×50

Thank you. Is it possible to create a left skewed distribution from the distribution above? I can't seem to find any resources on this.

rand creates a uniform distribution. You might look into the pearsrnd function, as that lets you define your distribution by setting the mean, standard deviation, skewness and kurtosis.
