  Anomalous diffusion phenomenon is an intriguing process that tracer diffusion
presents in numerous complex systems. Current experimental and theoretical
investigations have reported the emergence of random diffusivity scenarios
accompanied by the heterogeneity of the $\alpha$-anomalous diffusion exponents.
In this framework, we investigate a heterogeneous ensemble of tracers governed
by scaled Brownian motion (sBm). The heterogeneous features are considered on
anomalous diffusion exponent and diffusivity. To analyse such systems, we
introduce the truncated-Gaussian and truncated chi-squared distributions for
anomalous exponents in the superstatistical framework. We also discuss the role
of different temporal scales in sBm for our model. Furthermore, we investigate
the effects of coupling between diffusivity and anomalous exponent on
superstatistics of sBm. The investigation provides a thorough analysis of
simulation and analytical results.
