We derive constraints on cosmological parameters from $17$ uncorrelated BAO measurements that were collected from $333$ published data points in the effective redshift range $0.106 \\leq z \\leq 2.36$. We test the correlation of the subset using random covariance matrix. The $\\Lambda$CDM model fit yields the cosmological parameters: $\\Omega_m = 0.261 \\pm 0.028$ and $\\Omega_\\Lambda = 0.733 \\pm 0.021$.
